OPINION
for the Court.
She was jumping rope in front of her house. It was an early evening in May when an armed gunman in a hooded sweatshirt approached her in front of 95 Congress Avenue in Providence. He shot her several times at close range. She was rushed to Rhode Island Hospital, where she died the next day from multiple gunshot wounds to her head and neck. She was an eyewitness to the murder of Hector Feliciano (Feliciano), and she was under subpoena to testify in a murder trial that was scheduled to commence the next day. Her name was Jennifer Rivera (Jennifer). She was fifteen years of age. Jennifer was killed in order to prevent her from testifying against Charles Pona (Pona or defendant), 1 the defendant in this case, who was charged with and awaiting trial on the Feliciano murder. 2 In the course of the ensuing police investigation, three individuals — the defendant, Dennard Walker (Walker), the defendant’s half-brother, 3 and Miguel Perez (Perez) — were discovered to have planned and participated in Jennifer’s murder. 4
The defendant appeals from a judgment of conviction for first-degree murder, conspiracy, obstruction of justice, and numerous firearms counts. On appeal, defendant assigns a plethora of error: (1) the trial *459 justice abused his discretion in admitting various items of evidence, including evidence that defendant committed the Felici-ano murder; (2) the trial justice’s jury instructions on evaluating witness credibility were insufficient because they failed to highlight the danger of the testimony of accomplice witnesses who cooperate with the state; (3) the trial justice erred in rejecting defendant’s Batson 5 challenge to the state’s use of a peremptory challenge; (4) the trial justice impermissibly permitted the state to vouch for the truthfulness of two of its witnesses; and, finally, (5) the trial justice erred in denying defendant’s motion for a new trial. We affirm the judgment.
Facts and Travel
The events that precipitated this tragic crime began on August 28, 1999, when defendant shot and killed seventeen-year-old Feliciano in the vicinity of Congress Avenue in Providence. Providence police detective-sergeant James Marsland (Det.Marsland) was the lead detective on the Feliciano-murder investigation. Detective Marsland identified Jennifer as an important witness to this homicide, and he obtained a formal statement from her. She identified defendant from a photo array; she was the sole eyewitness. Based on his investigation, Det. Marsland drafted a warrant for defendant’s arrest, and Jennifer testified at defendant’s bail hearing.
During her testimony at the bail hearing, with defendant and Perez present, Jennifer disclosed her home address — 95 Congress Avenue — and testified that she was home on the night of the Feliciano murder and that she heard gunshots, looked out the window, and saw a lone gunman, whom she later identified as defendant, flee the scene. Although defendant initially was ordered held without bail, he subsequently would be released. He was indicted for Feliciano’s murder, and the trial was slated to begin on May 22, 2000. Jennifer was listed as a prosecution witness and was under subpoena to appear and testify.
While incarcerated at the Adult Correctional Institutions (ACI) awaiting trial on the Feliciano murder, defendant shared a cell with inmate Dennis Fullen (Fullen), who later testified against him. The record reveals that defendant and Fullen occasionally would discuss the Feliciano murder. Although defendant mentioned possibly paying Jennifer to refrain from testifying against him, he also told Fullen “that he had to dump her” and “that he wanted to get rid of her.” The defendant explained that he wanted Walker and Perez to kill Jennifer, and he expressed anger that Walker had been unable and Perez seemed unwilling to comply. Additionally, defendant expressed his hope for release on bail, so that he could “make sure it got done right.”
During this pretrial confinement, Perez visited defendant; during these visits, they would discuss defendant’s upcoming murder trial, and Jennifer in particular. The defendant explained to Perez that Jennifer “has got to go” and that Walker “need[ed] to handle that.” These admonitions were not ignored; on one occasion, upon observing Jennifer walking down a street, Perez exited his vehicle and fired his gun in the air in an effort to intimidate her. When *460 Perez related this encounter to defendant, however, he told defendant that he had been attempting to kill Jennifer, but that the gun had jammed. An angry defendant characterized this effort as “dumb” because it potentially alerted Jennifer that she was in danger. The defendant eventually was released on bail on April 22, 2000, one month before Jennifer was killed.
In the early afternoon of May 21, 2000, defendant, Walker, and another friend drove to Lockwood Plaza, where they met Perez. The defendant told Perez that Jennifer was outside of her house. Walker displayed a weapon, and defendant asked Perez if he had a vehicle they could use. Later that day, after Perez secured a vehicle, he drove defendant and Walker to the vicinity of Congress Avenue, where Jennifer lived. As Perez drove by Jennifer’s house, defendant and Walker spotted Jennifer. At that point, Perez turned the vehicle onto a series of side streets in order to pass by Congress Avenue once more. When the vehicle made its way back to Congress Avenue, Perez saw Jennifer jumping rope with a group of girls. Perez stopped on a nearby street, and Walker exited the vehicle. The defendant told Walker, “[M]ake sure you do it right.” Walker responded, “I can’t let you do life[.]”
Walker then made his way to 95 Congress Avenue; he walked up to Jennifer and shot her multiple times at close range. 6 Shortly after hearing gunfire, Perez saw Walker return to the vehicle and heard him declare, “I got her.” Jennifer was rushed to Rhode Island Hospital, where she died from multiple gunshot wounds the next day — which would have been the first day of defendant’s trial for the Feliciano murder. The trial did not go forward as scheduled.
Detective-sergeant Vincent Mansolillo (Det.Mansolillo) oversaw the investigation of this homicide. Apparently, Perez had been arrested on urn-elated drug charges, and Det. Mansolillo took the opportunity to discuss Jennifer’s murder. At first, Perez was untruthful and unresponsive, but eventually he admitted his participation and implicated Walker and defendant. During the course of the investigation, a search of Perez’s prison cell at the ACI, pursuant to a warrant, produced an incriminating letter addressed to Perez and penned by Pona.
Detective Mansolillo also met with inmate Fullen, who was then sharing a prison cell with Walker, who was in jail on an unrelated robbery charge. After giving a recorded statement, Fullen agreed to allow a recording device to be planted in his cell to record his conversations with Walker. During one conversation, Fullen and Walker discussed the circumstances of Jennifer’s murder. Walker disclosed that he was with defendant and Perez on the day of the murder and that defendant told Walker to kill her. Walker admitted that he shot Jennifer three times.
The defendant was indicted on August 30, 2002 for numerous offenses arising from the murder of Jennifer Rivera, including murder (count 1), conspiracy to commit murder (count 2), carrying a handgun without a license (count 3), committing a crime of violence while armed with a firearm (count 4), and obstruction of justice (count 5). The defendant was found guilty on all counts, but this Court vacated
*461
the conviction and remanded the case for a new trial.
State v. Pona,
Before defendant’s retrial in April 2010, several pretrial motions were litigated. First, defendant moved to exclude evidence of the cooperation agreements that Perez and Fullen had entered into with prosecuting authorities. Although the trial justice denied defendant’s motion and allowed the agreements as full exhibits, portions of them were redacted in a manner that was agreeable to the parties. Second, defendant requested a jury instruction relative to the credibility of accomplices and cooperating witnesses who testify for the state. The trial justice denied defendant’s request, explaining that the requested instruction was not required under this Court’s established caselaw.
Third, although the state agreed to redact portions of defendant’s letter to Perez, defendant requested that more of the letter be redacted. 7 Defense counsel argued that the language was irrelevant and highly prejudicial, in that it implied that defendant was incarcerated somewhere outside Rhode Island and that the detectives assigned to his case disbelieved his declarations denying any involvement in Jennifer’s murder. The state argued that the challenged portion of the letter was probative of defendant’s guilty state of mind and reflected the overall tenor of the entire letter: cautioning Perez not to divulge any information about Jennifer’s murder. The trial justice denied defendant’s request for further redactions, noting that, in his opinion, that portion of the letter was “very vanilla,” did not imply that defendant was imprisoned elsewhere, and was probative for the reasons articulated by the state.
The defendant also vigorously sought to exclude any reference to the Feliciano murder. The defendant argued that proof of a motive was not an essential element of the charges against him and that evidence of the Feliciano murder was therefore inadmissible under Rule 404(b) of the Rhode Island Rules of Evidence. The state responded that much of the evidence that this Court deemed overly prejudicial in
Pona I
would not be introduced, but it added that this Court acknowledged in
Pona I
that some evidence of the Feliciano murder was permissible in defendant’s retrial.
See Pona I,
The trial justice agreed with the state and held that the evidence of the Feliciano murder would not be excluded in its entirety because it was relevant to show motive and defendant’s specific intent to have Jennifer killed. After carefully chronicling our decision in
Pona I,
the trial justice permitted evidence that Jennifer emerged as the key witness in the Felici-ano-murder investigation; that she testified at defendant’s bail hearing and identified him as the man she saw fleeing from
*462
the murder scene; and that she was under subpoena to testify at the upcoming trial on the day she was killed. At the same time, however, the trial justice ruled that the tape of the bail hearing would not be played for the jury and that the state could not introduce certain physical evidence from the Feliciano murder — namely, the pager and fingerprints that this Court found objectionable in
Pona I. See Pona I,
During jury selection, the state exercised a peremptory challenge to excuse Juror 156, a prospective juror of Hispanic descent. In the course of the voir dire, the prosecutor informed the trial justice and defense counsel that he previously had prosecuted Juror 156’s cousin and that the trial justice had presided over those proceedings. Although the juror stated that he and his cousin do not speak and indicated that he could be fair to defendant and had no hesitation about sitting as a juror in this case, the prosecutor, at a sidebar conference, expressed his belief that the juror should be excused. However, while acknowledging the prosecutor’s concerns, the trial justice declined to excuse the juror for cause. The state then exercised a peremptory challenge to excuse Juror 156, and defendant raised a Batson argument in response. The trial justice noted that the juror was of Hispanic descent, and he inquired of the prosecutor whether he had a race-neutral reason for the strike. The prosecutor submitted that he exercised a peremptory challenge because, fifteen years earlier, he had prosecuted the juror’s cousin. The trial justice agreed that the prosecutor had a “completely plausible, credible and rational” race-neutral reason for the strike, and he accordingly overruled defendant’s Batson challenge.
In his opening statement, the prosecutor recounted the murder of Feliciano and the ensuing police investigation; he also described how Jennifer came to be the key eyewitness after identifying Pona as the perpetrator. The defendant renewed his Rule 404(b) objection to the evidence referenced in the prosecutor’s opening statement, requested a cautionary instruction, and moved to pass the case. The trial justice denied the motion to pass, but he instructed the jury that, although they would hear evidence about the Feliciano murder and that defendant had been indicted for that crime, he was not on trial for that murder and that the jury could only consider this evidence for the limited purpose of showing defendant’s intent, plan, or motive to kill Jennifer.
In the state’s case-in-chief, Det. Mars-land testified, over objection, that he drafted the warrant for defendant’s arrest on the Feliciano murder; that defendant was arrested for that murder; that Jennifer testified at his bail hearing in connection with the Feliciano case; and that she had identified defendant as the perpetrator. At the conclusion of the state’s direct examination of Det. Marsland, the trial justice reminded the jury that defendant was not on trial for the Feliciano murder and that the Feliciano evidence was offered only for the limited purpose of showing defendant’s intent, plan, or motive to kill Jennifer.
Stephen Mokler (Mokler), a former investigator in the Special Investigations Unit at the ACI, also testified for the state. During cross-examination, defense counsel asked Mokler whether Fullen had “serious enemy issues” at the ACI, necessitating a transfer to the High Security Segregation Unit; Mokler responded in the affirmative. On redirect examination, Mokler testified, this time over defendant’s objection, that Fullen had been transferred to protective custody and that this transfer was related to Fullen’s “enemy *463 issues.” The defendant moved to pass the case, arguing that evidence that Fullen was in protective custody was highly prejudicial because it implied that the witness needed protection from defendant. The trial justice denied the motion, explaining that “[t]he record is clear from this witness that the purpose of sending Fullen to protective custody was to deal with the enemy issues that [Mokler] had testified to in the first instance.”
For his part, Fullen testified about his discussions with defendant when the two were cellmates, and his cooperation agreement was introduced over defendant’s objection. Significantly, the trial justice instructed the jury that the cooperation agreement was not being “offered as substantive evidence that Mr. Fullen is, or has, or will testify truthfully] in this case.”
Perez also testified at length for the state. Again over defendant’s objection, the state introduced, as a full exhibit, the cooperation agreement between Perez and the state. The trial justice instructed the jury that the cooperation agreement was not being offered as substantive evidence that Perez had or would testify truthfully. Over defendant’s objection, Perez testified that he named defendant as a co-conspirator when he pled guilty to Jennifer’s murder. At that point, the trial justice reminded the jury that Perez had pled guilty to the crimes for which defendant was now on trial, but that fact was not substantive evidence of defendant’s guilt and was only being offered for the limited purpose of assessing Perez’s credibility. Additionally, Perez testified, over objection, that he remembered when defendant was arrested for the Feliciano murder and that he was present at defendant’s bail hearing when Jennifer testified. The trial justice reminded the jury, yet again, that evidence of the Feliciano murder was being offered for the very limited purpose of showing defendant’s intent, plan, or motive to kill Jennifer.
Perez also provided graphic testimony concerning the events leading up to Jennifer’s murder. According to Perez, on May 21, 2000, before going to Jennifer’s house, the group talked about exacting retribution from a member of the Lassiter family for the death of one of their friends a month earlier. Perez told the jury that Walker declared that “[h]e wanted to get one of [the Lassiters].” The witness was permitted to testify, over defendant’s objection, that Walker wanted “[t]o retaliate for what [the Lassiters] did to our friend.” When the prosecutor asked Perez what had happened to the friend, the trial justice sustained defendant’s objection and instructed the prosecutor to pursue another line of inquiry. Later in his testimony, Perez stated that, on May 21, 2000, they planned to “[s]ee if [they] bumped into one of the Lassiters” in the Elmwood Avenue area before heading to Jennifer’s house. Perez further testified, without objection, that the group drove to the Elmwood Avenue area, but, finding no Lassiters, proceeded to Jennifer’s house on Congress Avenue. Finally, defendant’s letter to Perez was admitted, over defendant’s objection, as a full exhibit, and the portion of the letter to which defendant had previously objected was read into evidence. 8
The state also called Walker in its casein-chief; but it readily became apparent that he was a hostile witness. 9 ' Although admitting that he was the triggerman in Jennifer’s murder, Walker relayed a very different version of that murder than what Perez recounted. According to Walker, he *464 was riding in a car by himself just before he murdered Jennifer outside of her home; he testified that he acted alone and never spoke to defendant about his murderous intentions. Walker testified that his statements to Fullen in the recorded conversation — in which he declared that he was with Perez and defendant on the day of the murder — were not accurate. Additionally, although he acknowledged that during his plea colloquy he admitted his guilt and alluded to defendant’s participation in the crimes against Jennifer, Walker insisted that the facts that were placed on the record during his plea colloquy were admitted as true only as they related to Walker’s involvement in the murder.
At the close of the state’s case, defendant’s motion for judgment of acquittal on the firearms counts was denied. The defendant renewed his request for a jury instruction concerning the credibility of cooperating witnesses. The trial justice denied this request, but he noted that defendant’s objection would be “preserved for purposes of [the] instructions.” Although the trial justice did not give the instruction defendant sought, he nevertheless provided the jury with comprehensive instructions for assessing witness credibility, which highlighted the need for the jury to focus on “the interest or lack of interest of the witness, if any, in the outcome of the case, and the bias or the prejudice of the witness, if any, as well as any criminal record that a witness may have.” The instructions also informed the jury that it “may consider whether a witness would have a motive to be truthful or untruthful in his or her testimony.” The trial justice’s final charge to the jury also included yet another cautionary instruction on the limited purpose of other-crimes evidence.
During the state’s closing argument, the prosecutor reminded the jury about the cooperation agreements of Perez and Ful-len, the promises to tell the truth, and the harsh consequences for failure to do so. Specifically, the prosecutor told the jury the following:
“There’s no reason for the police or the Attorney General’s Office to want a person to implicate a person who didn’t do anything. And that’s why the cooperation agreement says if you’re caught telling a lie, either if you’re questioned by the police, by the Attorney General’s Office, by the defense lawyer or by the Court, any party involved, you can get the maximum sentence allowable on your offenses, the agreement is null and void, you can get charged with perjury in addition to the charges you already have.
“So these cooperation agreements are there for the protection of everyone involved, the defendant, the Court, the State, and the defense. And it shows you exactly what these people [Fullen and Perez] were operating under at the time they provided information. They told the truth and they received a reward if they did for their cooperation.”
The defendant made no objection to these comments.
The defendant was found guilty on all counts in the indictment. The trial justice denied defendant’s motion for a new trial, concluding that the jury’s verdict was “wholly justified by the credible evidence in this case.” He found the testimony of Fullen and Perez to be “unvarnished and unembellished * * *, in a word, credible.” This testimony, he concluded, amply supported the jury verdict. By contrast, the trial justice deemed Walker’s testimony to be “perjury,” and “pathetic and desperate”; he concluded that “no rational juror charged with the responsibility of judging credibility would or could rely on Walker’s specious and inane trial testimony.”
*465 The trial justice sentenced defendant to life imprisonment for Jennifer’s murder and ten years for conspiracy to commit murder, to be served concurrently. He also sentenced defendant to ten years on count 3, carrying a pistol without a license, to be served consecutive to the sentences imposed on counts 1 and 4. On count 4, using a firearm during the commission of a crime of violence, the trial justice imposed a ten-year sentence, to be served concurrently with the sentence imposed on count 1. Finally, defendant received a five-year concurrent sentence for obstruction of justice. All sentences imposed in this case were ordered to run consecutive to the life sentence that defendant received for the Feliciano murder. The defendant appeals.
Issues Presented
The defendant’s appellate contentions can be separated into five categories. First, defendant argues that the trial justice abused his discretion in admitting an array of what he asserts was highly prejudicial evidence. Specifically, defendant assigns error to the trial justice’s decision to admit: (1) evidence concerning defendant’s involvement in the Feliciano murder; (2) evidence that defendant, Perez, and Walker were searching for one or more of the Lassiters before proceeding to Jennifer’s house to kill her; (3) a portion of the letter from defendant to Perez that was seized from Perez’s ACI cell; and (4) testimony that Fullen was placed in protective custody. Second, defendant urges this Court to adopt a rule requiring trial justices to give a special instruction about accomplice witnesses if requested or, in the alternative, to hold that the trial justice’s instructions in this ease were insufficient to apprise the jury of the dangers of the testimony of accomplices who cooperate with the state. Third, defendant claims that the trial justice erred in rejecting his Batson challenge to the prosecutor’s decision to strike a prospective juror of Hispanic descent. Fourth, defendant contends that the trial justice allowed the state to impermissibly vouch for the truthfulness of Fullen and Perez. Finally, defendant argues that the trial justice erred in denying his motion for a new trial. We address each contention in turn.
Analysis
I
Evidentiary Issues
The defendant argues that the trial justice abused his discretion in failing to exclude, under Rules 403 and 404(b) of the Rhode Island Rules of Evidence, several items of evidence. “[I]t ‘is well settled that we review a trial justice’s decision admitting or excluding evidence under an abuse of discretion standard.’ ”
State v. Brown,
Generally, Rule 404(b)
10
“prohibits the use of evidence of prior bad acts, wrongs, or crimes ‘to show the defendant’s propensity to commit the crime with which he [or she] is currently charged.’ ”
Dubois,
*466
We recognize, of course, that “[t]he line between Rule 404(b) evidence presented for the impermissible purpose of demonstrating propensity and Rule 404(b) evidence presented for one of the specific non-propensity exceptions is ‘both a fine one to draw and an even more difficult one for judges and juries to follow.’ ”
Rodriguez,
Rule 404(b) does not represent the only hurdle a proponent of other-acts evidence must surmount.
Pona I,
“Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence.” Rule 403.
However, “a trial justice’s discretion to exclude evidence under Rule 403 must be used sparingly. * * * It is only when evidence is marginally relevant and enormously prejudicial that a trial justice must exclude it.”
Smith,
A. The Feliciano Murder
The defendant’s first assignment of evidentiary error must be assessed in light of our decision in
Pona I.
In defendant’s first trial, the state introduced an abundance of evidence concerning defendant’s involvement in Feliciano’s murder to a degree that amounted to reversible error.
Pona I,
*467
In vacating defendant’s conviction, this Court concluded that the use of this evidence constituted reversible error.
Pona I,
“[T]he Superior Court erred when it did not attempt to strike a balance between the necessity of admission and the danger of unfair prejudice occasioned by the wholesale adoption of the bail-hearing testimony. This type of evidence must be received ‘with great caution,’ and a careful review of her testimony reveals that there are particular statements that should have been excluded.” Id. at 953 (quoting State v. Peters,86 R.I. 447 , 450,136 A.2d 620 , 621 (1957)).
We cautioned that “references to the murder of Feliciano should have been kept to a minimum.” Id.
However, nothing we said in
Pona I
suggested that all reference to the Felici-ano murder was off-limits. By contrast, we recognized that it was “undisputed that Walker lolled Jennifer for the sole reason of preventing her from testifying against defendant.”
Pona I,
“[T]here is no question that [Jennifer’s] testimony at [defendant’s] bail hearing, and the fact that she was to testify when he was tried for murdering Feliciano, led to her being Wiled. * * * We agree that reference to her testimony was reasonable to demonstrate the event that precipitated her tragic death. * * * Although we will not go so far as to deny the prosecution the opportunity to make any reference to the fact that defendant was charged with murder, we nonetheless hold that the quantum of evidence admitted here was extremely prejudicial to defendant and requires reversal.” Id. at 953.
Because it was the quantum of evidence of the Feliciano murder, and not straightforward proof of defendant’s involvement in that crime, that this Court declared to be reversible error, proof of defendant’s arrest and Jennifer’s connection to the prosecution was highly relevant and clearly not off-limits.
In this case, the trial justice ably followed our admonitions in Pona I. The quantum of evidence of the Feliciano murder introduced in the retrial radically was reduced from that in Pona I. The photo-pack, the pager, and the fingerprint evidence were not admitted. The jury did not hear Jennifer’s “voice from the grave.” Instead, references to the Feliciano murder appropriately were minimal. Detective Marsland testified that he was involved in the investigation and that it was Jennifer who identified defendant as the man she saw fleeing the murder scene. He also related that Jennifer testified at defendant’s bail hearing — with defendant and Perez in attendance — and that she was under subpoena to testify against defendant at a trial scheduled to commence the day after she was shot. In sum, the trial justice struck the appropriate balance; he allowed evidence of Jennifer’s involvement in the Feliciano investigation — which was necessary to understand defendant’s mo *468 tive and intent — and excluded evidence that related solely to the prior murder itself, which had no probative force — save for inviting the jury to engage in propensity-based reasoning to conclude that, because defendant was guilty of killing Feli-ciano, he had also killed again. 11
The defendant is not entitled to a sanitized version of the state’s evidence against him; he is guaranteed a fair trial. The record demonstrates that the trial justice carefully instructed the jury on four occasions that the evidence of the Feliciano murder was being admitted for the sole purpose of demonstrating defendant’s motive, intent, or plan to kill Jennifer. Therefore, in addition to carefully separating the evidence of the Feliciano murder that would be admitted from the evidence that would be excluded, the trial justice safeguarded against the danger that the jury would use this evidence to engage in impermissible propensity-based reasoning.
For these reasons, we conclude that the trial justice did not abuse his discretion in admitting evidence showing defendant’s involvement in the Feliciano murder.
B. Looking for a Lassiter
The defendant next asserts that the trial justice erred in allowing evidence that defendant, Walker, and Perez first went looking for a member of the Lassiter family, intending to exact retribution for a friend’s death, before they proceeded to 95 Congress Avenue to kill Jennifer. The defendant argues that this evidence was irrelevant, needlessly confusing, and highly prejudicial, since it permitted the jury to infer that these men were a murderous bunch. Having carefully reviewed the record, we are satisfied that this issue is not properly before us.
“According to our well settled ‘raise or waive’ rule, if an issue was not preserved by
specific
objection at trial, then it may not be considered on appeal.”
State v. McManus,
At the outset, we note that, without objection, Perez was permitted to testify that, on the day Jennifer was murdered, he, defendant, and Walker discussed “guys that killed one of our friends the month before” and that those “guys” were the Lassiters. The prosecutor then asked, “And what was it about the Lassiters that either you or [Walker] or [defendant] was talking about?” The defendant objected, and the prosecutor offered to rephrase the question. Perez then testified, without objection, that Walker declared that “[h]e wanted to get one of [the Lassiters].” Perez also testified, again without objection, that before going to 95 Congress Avenue, the group went to “[s]ee if [they] bumped into one of the Lassiters[.]” Likewise, Perez testified, without objection, *469 that he, defendant, and Walker went to a gas station on Elmwood Avenue, did not encounter any Lassiters, and then proceeded to 95 Congress Avenue.
To be sure, defendant posed some objections to this line of inquiry. For example, after Perez stated that Walker “wanted to get one of [the Lassiters],” the prosecutor asked, “How come?” The defendant objected, and the trial justice overruled the objection. Perez answered, “To retaliate for what they did to our friend.” After the prosecutor asked Perez what happened to their friend, defendant’s objection was sustained. Similarly, when the prosecutor asked Perez about where the group planned to search for a Lassiter, defendant’s objection was overruled. Perez then testified that the trio planned to look for the Lassiters at a gas station on Elm-wood Avenue.
However, these objections were general in scope; at no point did defendant state the basis for the objection, let alone make an argument centered on Rule 403. Moreover, Perez gave the most critical portions of his testimony about the Lassiters — that the Lassiters had killed one of their friends the month before, that Walker “wanted to get one of them,” and that the group actually went looking for the Lassi-ters — in the absence of any objection.
Additionally, much of the same evidence also was admitted, without objection, during Walker’s testimony. Walker acknowledged that he told Fullen that he, defendant, and Perez were “looking for a Lassiter” on the day he murdered Jennifer. Similarly, the prosecutor read for the jury the statement of facts accompanying Walker’s guilty plea; these facts included that Walker wanted revenge for the death of one of their friends at the hands of the Lassiters and that, before proceeding to Congress Avenue to kill Jennifer, the group went looking for Kendall Lassiter. Walker testified that, at the time of his plea, he acknowledged in open court that this statement of facts was true. The defendant lodged no objection to any of this testimony.
We are of the opinion that defendant’s objections to this evidence, to the extent any were made, were not sufficiently focused to alert the trial justice to a Rule 403 basis for exclusion of the evidence. Coupled with defendant’s failure to object to the critical portions of this evidence, defendant’s general objections did not preserve his Rule 403 argument for our review.
See State v. Feliciano,
C. Pona’s Letter to Perez
The defendant also claims that the trial justice erred in admitting the following portion of his letter to Perez:
“Yo[J these [d]etectives try to come down here and see me[,] talking about they know I was there when that broad got hit. I was like[, ‘Y]o, I don[’]t know nothing[.][I]f you got so much[,] why you questioning me about it[?’] They was like[, ‘C]ome on[, M]anny[,] you know something[.’] I was like[, T]ou came all the way down here for nothing. Whatever is whatever. [’]”
The defendant contends that this excerpt was highly prejudicial because: (1) the phrase “you came all the way down here” suggested that defendant was incarcerated outside the state “because he was a dan *470 gerous man”; and (2) it related defendant’s impi'ession that the detectives did not believe his denials, which would tend to “encourage the jury to base its decision on the disbelief of the detectives.” This danger of unfair prejudice, defendant argues, when coupled with the marginal relevance of this evidence, required exclusion under Rule 403. 12 We disagree.
In denying defendant’s motion in limine to exclude this portion of defendant’s letter, the trial justice remarked that the evidence was “very vanilla”; he found that the phrase “came all the way down here” just as easily could mean that the detectives needed to travel “all the way down” to the ACI to speak with defendant. We are in full agreement with the trial justice’s assessment of the prejudice of this letter. Moreover, contrary to defendant’s assertion, this portion of the letter was more than marginally relevant; it conveyed to Perez that he too should not cooperate in the investigation of Jennifer’s murder, thereby tending to establish defendant’s guilty state of mind. We are satisfied that the trial justice did not abuse his discretion in permitting this evidence to come before the jury.
D. Fullen in Protective Custody
The final instance of claimed evi-dentiary error concerns Mokler’s testimony that Fullen was placed into protective custody at the ACI. The defendant contends that this evidence tended to suggest that Fullen required protection from defendant and was, therefore, unfairly prejudicial. This contention misses the mark.
The state did not elicit this testimony from Mokler until after defendant opened the door to this topic. It was defense counsel who inquired about Fullen’s “serious enemy issues” at the ACI. On redirect examination, Mokler testified that Fullen was transferred to protective custody and that this transfer was related to these same “enemy issues.” In denying defendant’s motion to pass the case, the trial justice explained that “[t]he record is clear from this witness that the purpose of sending Fullen to protective custody was to deal with the enemy issues that [Mokler] had testified to in the first instance.” We agree with the trial justice that no unfair prejudice flowed from this testimony, and we discern no abuse of discretion in denying the motion to pass and admitting this evidence.
II
Accomplice Instruction
The defendant also assails the trial justice’s refusal to instruct the jury about the dangers of testimony from accomplices who cooperate with the state. When we are called upon to review “issues pertaining to jury instructions, we do so
de novo.” State v. Vargas,
We repeatedly have held that “it is not necessary for a trial justice to give an accomplice charge.”
State v. Drew,
The defendant candidly acknowledges this substantial body of caselaw, but he nevertheless entreats us to overrule it. We were confronted with a similar importunity in
Drew,
In this case, defendant attempts to portray this issue in a different light. He contends that the trial justice’s instructions, unlike the instructions in Drew, Sivo, Fenner, and DeMasi, did not name the cooperating accomplices — Perez in particular — or remind the jury that cooperation with authorities in exchange for promises of leniency may influence such a witness’s testimony. According to defendant, the possibility that some trial justices may name the cooperating accomplices in their instructions, while others do not, presents a sufficiently serious inconsistency to warrant overruling our precedent. We are unconvinced.
The trial justice provided the jury with a comprehensive instruction on evaluating witness credibility; it included:
“You should consider the interest or lack of interest of the witness, if any, in the outcome of the case, and the bias or the prejudice of the witness, if any, as well as any criminal record that a witness may have.
“You may consider whether a witness would have a motive to be truthful or untruthful in his or her testimony, and you may further consider the probability or the improbability of the truth of a witness’s testimony.”
The trial justice thus alerted the jury to the possibility that a witness’s interest in the case, or his bias or motive to be untruthful may impact that witness’s credibility. Our caselaw requires nothing more.
Clearly, the trial justice did not specifically identify Perez or mention the fact of his cooperation agreement with the state during this instruction — nor was he required to do so. By the close of the evidence, the jury hardly could be expected to overlook Perez’s testimony. As the *472 crucial witness for the state, Perez offered the most damning of all the testimony about defendant’s involvement in Jennifer’s murder. Additionally, the state’s cooperation agreements with both Fullen and Perez were admitted as full exhibits, and defense counsel extensively cross-examined both witnesses on the promises they received from the state in exchange for their cooperation. Moreover, as our caselaw on this issue envisions, defense counsel vigorously argued during closing argument that the promises Perez and Fullen received in exchange for their testimony should lead the jury to evaluate their credibility with skepticism. Therefore, we are satisfied that defendant’s assertion of instructional error is without merit.

Batson Challenge
The defendant next attacks the state’s use of a peremptory challenge to excuse a juror of Hispanic descent. The Equal Protection Clause of the Fourteenth Amendment to the United States Constitution “guarantees the defendant that the State will not exclude members of his [or her] race from the jury venire on account of race[.]”
State v. Pona,
We have remarked that the “decisive question” in a
Batson
inquiry “will be whether counsel’s race-neutral explanation for a peremptory challenge should be believed. There will seldom be much evidence bearing on that issue, and the best evidence often will be the demeanor of the attorney who exercises the challenge.”
Price,
In this case, we will assume that defendant satisfied Batson’s first step. Although the trial justice did not state explicitly whether defendant satisfied this first prong, he noted that the excused juror was of Hispanic descent,
13
and he inquired of the prosecutor whether a race-
*473
neutral reason existed for the strike. The trial justice next proceeded to rule on the ultimate question of discrimination. “[T]hus, ‘the preliminary issue of whether [] defendant had made a
prima facie
showing [became] moot.’ ”
Pona,
The defendant argues, as he did below, that the fact that the juror stated that he “never” spoke with his cousin, who had been prosecuted by the prosecutor, demonstrates that the prosecutor’s articulated reason for the strike was pretextual. However, the trial justice found, without hesitation, that the prosecutor properly set forth a race-neutral reason for the strike and that he did not harbor a racially discriminatory purpose, explaining that “[t]he fact remains that the State of Rhode Island * * * prosecuted this man’s cousin. That’s reason enough for me, on its face, to allow [the prosecutor] to exercise a challenge. I find that the reason for doing so is completely plausible, credible and rational.”
The defendant has offered no reason, save for critiquing the persuasiveness of the articulated rationale, for us to disturb the trial justice’s appraisal of the prosecutor’s state of mind — an evaluation we accord “great deference.”
Price,
*474 IV
Vouching
We next turn to defendant’s contention that the state impermissibly utilized the cooperation agreements between the state and Fullen and Perez to suggest that the state had special knowledge that Fullen and Perez were testifying truthfully. In this context, we have remarked that “[o]ne means through which improper vouching may occur is by admission of plea agreements phrased in a manner that suggests that the government has special knowledge that its witness is speaking the truth.”
State v. Diefenderfer,
In this case, defendant focuses on the state’s use of the cooperation agreements during closing argument. The defendant argues that by referencing the portion of the cooperation agreements that warned of reinstatement of the maximum allowable sentence and perjury charges for failure to testify truthfully, the state suggested that it had special knowledge that Fullen and Perez were truthful; because the jury was led to believe that the witnesses had been given the benefit of their bargain and had not been prosecuted for perjury, the argument goes, the state improperly vouched for the truthfulness of these witnesses. We reject this contention.
At the outset, we note that defendant has failed to preserve any challenge to the prosecutor’s closing argument. The defendant made no objection to the now-challenged remarks. To preserve “the issue of prejudicial impropriety in a closing argument, a defendant must not only make an objection at the time when the allegedly improper comment is made, but he or she must also make a request for a cautionary instruction or move for a mistrial.”
State v. Fortes,
The defendant vigorously disputes this conclusion, arguing that, because he raised a pretrial objection to the admissibility of the cooperation agreements, which the trial justice stated would be “protected,” and renewed this objection before each cooperation agreement was. admitted, this issue has been preserved. We disagree. The defendant’s objections before and during trial concerned the admissibility of the agreements. The defendant raises a different appellate challenge; he does not claim simply that the cooperation agreements should have been excluded, but instead argues that the prosecutor, while referencing the agreements in his closing argument, improperly vouched for the truthfulness of Fullen and Perez. Clearly, the trial objections did not encompass the now-challenged comment during closing argument.
In any event, this aspect of defendant’s appeal, even if it had been preserved, is without merit. To the extent defendant attempted to lodge an appellate attack on the admissibility of the coopera
*475
tion agreements themselves, the trial justice’s decision is amply supported by our decision in
Diefenderfer.
Although the cooperation agreements require truthfulness on the part of the cooperating witnesses and warn that perjury charges will be initiated if the witnesses give false testimony, these statements, standing alone, do not constitute improper vouching.
See Diefenderfer,
In the face of this established law, defendant focuses in this appeal on the prosecutor’s statements during closing argument. In support of his position, defendant cites to the Ninth Circuit’s decision in
United States v. Roberts,
We are not persuaded. The prosecutor’s gas-chamber statement in
Roberts
was not the basis for the court’s finding of impermissible vouching; rather, the impermissible vouching arose from the prosecutor’s statement that a state-police officer had attended the trial on “a mission * * * to sit and listen to the testimony of [the cooperating witness].”
Roberts,
V
Motion for New Trial
Finally, we turn to defendant’s contention that the trial justice erroneously denied his motion for a new trial. “When a trial justice considers whether the verdict is against the weight of the evidence, he or she sits as the legendary thirteenth juror; and, in light of the charge to the jury, must exercise his or her independent judgment in weighing the evidence and assessing the credibility of the witnesses.”
Smith,
Our review of a trial justice’s ruling on a motion for a new trial is deferential; “[i]f the trial justice has complied with this procedure and articulated adequate reasons for, denying the motion, his or her decision will be given great weight and left undisturbed unless the trial justice overlooked or misconceived material evidence or otherwise was clearly wrong.”
Smith,
In this case, defendant assails the trial justice’s credibility determinations; he contends that Perez and Fullen were not worthy of belief because their cooperation with the state colored their testimony and, conversely, that Walker, who had no motive to testify against Pona to receive favorable treatment, should have been deemed credible. Additionally, defendant argues that the criminal records of Fullen and Perez make their testimony suspect, and he further points out that Perez gave inconsistent versions of Jennifer’s murder to police. We are unconvinced.
In the mine-run of cases, credibility battles are won or lost in Superior Court. A defendant’s disagreement with a trial justice’s credibility determinations “is not a sufficient basis to warrant the granting of a motion for new trial.”
Paola,
This case is no exception to this general rule. The trial justice recognized that Fullen and Perez each “arrived with baggage.” Nonetheless, the trial justice found their testimony to be “unvarnished and unembellished * * *, in a word, credible.” On the other hand, the trial justice deemed Walker’s testimony to be “pathetic and desperate” and characterized it as “perjury.” He found that “no rational juror charged with the responsibility of judging credibility would or could rely on Walker’s specious and inane trial testimony,” and he referred to Walker’s “mendacious lame efforts to exonerate [defendant].” The trial justice expressed his belief that, ironically, Walker “became the [s]tate’s strongest witness” because his testimony was “so absurd and so ridiculous.” In sum, the trial justice determined that “[t]he guilty verdicts in this trial were fully justified beyond any doubt.”
The defendant has failed to demonstrate that the trial justice, who observed firsthand the testimony of these witnesses, clearly erred or overlooked or misconceived relevant and material evidence. *477 Therefore, we affirm the trial justice’s denial of defendant’s motion for a new trial.
The End
After thirteen years, two trials, two appeals, and assorted collateral litigation, 14 the defendant and those responsible for cutting the life of this fifteen-year-old girl tragically short, in a brutal assault on our system of justice, have nonetheless been afforded the benefits of the constitutional process each sought to subvert. The defendant, Charles Pona, has had his day in court, and the rule of law has prevailed. The name “Jennifer Rivera” forever will be associated with virtue and valor. We affirm the conviction.
For the reasons articulated above, we close the final chapter in this chronicle. We affirm the judgment below and remand the papers to the Superior Court.
Notes
. The defendant subsequently was convicted of the first-degree murder of Feliciano and other offenses related to that murder.
State v. Pona,
. The record refers to Walker both as defendant’s half-brother and his brother.
. Both Walker and Perez pleaded guilty to the murder of Jennifer, along with other charges stemming from that murder. Walker, the undisputed triggerman in Jennifer's murder, received a sentence of life imprisonment.
. In
Batson v. Kentucky,
. Walker testified that he shot Jennifer "[plrobably like four times.” Perez testified that he heard three gunshots. Elizabeth La-posata, M.D. (Dr. Laposata), the state's chief medical examiner at the time of Jennifer's murder, performed the autopsy. Doctor La-posata determined that Jennifer suffered two gunshot wounds, one to the back of the head and one to the neck.
. Specifically, defendant requested that the following passage of the letter be excised:
"Yo[,] these [djetectives tiy to come down here and see me[,] talking about they know I was there when that broad got hit. I was like[, 'Y]o, I don[']t know nothing[.][I]f you got so much[J why you questioning me about it[?’] They was like[, 'C]ome on[, M]anny[,] you know somethingl)’] I was like[, 'Y]ou came all the way down here for nothing. Whatever is whatever. If you so call [sic] got a case[,] see me in Court[. 0]ther [than] that[,] I don’t have nothing else to say[.’ T]hey was saying mad shit[.]”
. That portion is set forth in footnote 7, supra.
. Unlike Perez, Walker had not entered into a cooperation agreement with the state.
. Rule 404(b) of the Rhode Island Rules of Evidence provides:
"Evidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show that the person acted in conformity therewith. It may, however, be admissible for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake or accident, or to prove that defendant feared imminent bodily harm and that the fear was reasonable.”
. Before this Court, defendant contends that “the [sítate and [defendant]
could have
stipulated that [Jennifer] was going to be a key witness for the [s]tate in an upcoming felony trial, for which he possibly faced a life term.” (Emphasis added.) Although the state could have agreed to such a stipulation, it was not required to do so. Moreover, although such a stipulation evidently was offered by defendant in his first trial,
State v. Pona,
. In his reply brief, defendant asserts that, to the extent that the letter relates what the detectives told defendant, it contains inadmissible hearsay. No hearsay argument was made at trial, however, and we will not entertain its debut on appeal.
. Although the challenged juror was not of the same race as defendant — an African-American male — this fact is irrelevant to the
Batson
inquiry; the United States Supreme Court has “eliminated the requirement that a criminal defendant share the same race as a challenged juror * *
