Retired:
Gene E. Watson appeals his conviction for attempted possession of marijuana, in violation of D.C.Code § 48-904.01(d) (2001). Appellant claims that the trial court erred in: (1) denying his motion to suppress drug evidence found in a search incident to an arrest he claims lacked probable cause, and where the prosecutor did not comply with Rule 16 discovery requirements prior to the suppression motion; and (2) admitting two statements appellant made, in violation of his Fifth Amendment rights. We conclude that none of appellant’s claims requires reversal and we therefore affirm his conviction.
I. Statement of Facts
On June 17, 2008, Metropolitan Police Department (MPD) Officer Chris Reisinger was on duty in a marked police cruiser on the Whitney Young Memorial Bridge. Officer Reisinger was operating a “Lidar III” device — a laser radar detection gun— to detect speeding cars. At approximately 6:00 p.m., Officer Reisinger saw appellant’s car traveling across the bridge “at a high rate of speed” and going “a lot faster than other vehicles.” The speed limit on the bridge, which was clearly indicated by two posted signs, was forty miles per hour. The officer testified that when he pointed his Lidar III device at appellant’s car, the gun sounded an audible target acquisition tone, locked on the vehicle, and indicated that the car was traveling at eighty-eight miles per hour — forty-eight miles over the posted speed limit. Officer Reisinger testified that he knew that driving thirty miles over the speed limit in the District of Columbia is an arrestable offense, so he signaled to appellant to pull over to the side of the road. Officer Reisinger ap *281 proached the driver’s side of the car and asked appellant (the sole occupant of the vehicle) for his driver’s license and registration information. Appellant produced a driver’s license and a D.C. fireman’s employee identification card. The officer then asked appellant to step out of the car, at which time he handcuffed appellant and informed him that he was under arrest for driving more than thirty miles over the speed limit.
Officer Reisinger then began to search appellant incident to the arrest, during which the officer pulled up appellant’s pant leg and noticed a bulge in appellant’s sock. The officer testified that “for safety reasons” he asked, “what’s that?” Appellant responded, “Oh, it’s just some weed.” Officer Reisinger recovered what he suspected to be crack cocaine and marijuana from appellant’s sock (both field-tested positive as drugs) as well as $1,387 from appellant’s pocket. Because of appellant’s status as a D.C. Fire Department employee, Officer Reisinger notified the fire department of appellant’s arrest. While waiting for the fire department officers to arrive and retrieve appellant’s employee identification card, Officer Reisinger asked appellant “standard biographical questions” for booking purposes, such as his name and date of birth. According to Officer Reisinger, appellant had not been prompted by a question when he volunteered that he had “just got it at Riggs Road, it’s for my girl.” Officer Reisinger did not respond to appellant’s statement. After the fire department officers arrived and appellant’s employee identification card was surrendered to them, appellant was taken to the police department.
Appellant was charged with one count of unlawful possession of cocaine, in violation of D.C.Code § 48-904.01(d), and one count of unlawful possession with intent to distribute marijuana, in violation of D.C.Code § 48-904.01(a)(l). However, because the forensic chemist who prepared the Drug Enforcement Administration’s (DEA) laboratory report was unavailable to testify at trial, the government amended the charges to one count of attempted possession of cocaine and one count of attempted possession of marijuana. Defense counsel filed a motion to suppress the statements under the Fourth and Fifth Amendments alleging that the incriminating statements were obtained during the course of an unlawful arrest and in violation of appellant’s Miranda 1 rights.
After hearing testimony from Officer Reisinger, the court denied appellant’s motion to suppress appellant’s two statements because appellant was “not specifically interrogated” and “it was legitimate for the officer, as he testified, [to be] concerned about his safety [and] to make sure that the item that he was going to attempt to retrieve from the sock area from the bulge in the sock did not contain something that could injure him.” The judge found appellant guilty of attempted possession of marijuana, relying on the “unrebutted” and “very credible” testimony of Officer Reis-inger, the fact that appellant had concealed the item which “is consistent with the items being illegal,” and the “very large amount of cash” found on appellant. The trial court also credited that appellant made the statements that the substance in the sock was marijuana and that he had purchased it for his girlfriend, which the court deemed sufficient evidence to establish that appellant was guilty of attempted possession of marijuana. 2 Due to the lack *282 of evidence regarding the substance suspected to be cocaine, the court acquitted appellant of that count. Appellant filed this timely notice of appeal.
II. Suppression of Physical Evidence
Appellant contends that the trial court erred in denying his motion to suppress evidence because the arrest, which led to Officer Reisinger searching him and finding the marijuana, was made without probable cause. Appellant maintains that the officer lacked probable cause because he unreasonably relied upon incompetent evidence to formulate his belief that the Lidar III device accurately recorded that appellant was driving thirty miles above the legal speed limit. Relatedly, appellant claims that the government violated D.C. Superior Court Rule of Criminal Procedure 16 in not providing to defense counsel certain documents “material to the preparation of the defendant’s defense,” which “relat[ed] to Reisinger’s testimony on his preparation for use of the Lidar III and ... regarding proper training, use and employment of the [L]idar.”
A. Probable Cause to Arrest
On appeal from a denial of a motion to suppress, our scope of review is limited.
See Womack v. United States,
A police officer conducting a traffic stop must have “a reasonable, articulable suspicion that he was witnessing a traffic violation” before he may stop a vehicle and its occupants.
Duckett v. United States,
We begin by noting that the government was not required to prove that appellant was in fact driving at a speed of eighty-eight miles per hour, or even that the Lidar III device was accurate in its calculation of the speed of his vehicle, as appellant was not prosecuted for speeding but for attempted possession of marijuana. Speeding at more than thirty miles over the posted speed limit is an arrestable offense.
See
18 DCMR § 2200.12. Thus, at the suppression hearing the government was required to prove that Officer Reising
*283
er had probable cause, or “reasonably trustworthy information ... to warrant a man of reasonable caution in the belief,”
Perkins,
The trial court credited the testimony of Officer Reisinger that when he pulled appellant over, he had observed appellant driving across the bridge at a rate significantly faster than the other cars. In addition to his visual observation, the officer aimed the Lidar III device at appellant’s car and saw a reading of eighty-eight miles per hour, forty-eight miles over the posted speed limit. Officer Reisinger testified that he had operated the Lidar III device for at least a couple of years, had been trained and certified by MPD in its use, had conducted the Lidar III device’s self-test earlier that day, which indicated that it was functioning properly, and knew that the device itself had recently been certified as accurately calibrated by an outside entity. In light of the officer’s testimony credited by the trial court, we agree with the trial court’s conclusion that it was reasonable for Officer Reisinger to believe that he had probable cause to arrest appellant for speeding.
See Perkins,
B. Rule 16 Discovery Violation
In a related claim, appellant contends that the government failed to produce a number of documents relating to Officer Reisinger’s training for and use of the Lidar III device, and the accuracy of the Lidar III device the officer used when he stopped appellant, that counsel had requested pretrial pursuant to Superior Court Rule of Criminal Procedure Rule 16. These documents, he claims, were necessary for counsel’s preparation for the suppression motion. We review the trial court’s discovery rulings for abuse of discretion,
United States v. Curtis,
In order to demonstrate materiality, appellant had to make a preliminary showing that the requested evidence was “material to the preparation of [his] defense, or [was] intended for use by the government as evidence in chief at the trial.” Super. Ct.Crim. R. 16(a)(1)(C). At the suppression hearing, defense counsel filed a motion in limine to exclude any evidence relating to the Lidar III device. Appellant’s Rule 16 discovery request included: (1) a certificate of calibration of the Lidar III device issued by the manufacturer; (2) documents indicating that Officer Reisinger had received at least four hours of training and was certified to operate the Lidar III device; (3) the officer’s written notes in connection with the incident; (4) any evidence tending to indicate that Officer Reisinger performed the daily tests recommended by the manufacturer before and after using the Lidar III device on the day he stopped appellant; and (5) any evidence tending to prove that Officer Reisinger made a visual estimate of the target vehicle’s speed. Appellant argued at the suppression hearing, as he also does on appeal, that these documents were material as they were “essential and pivotal to the officer’s formulation of probable cause.” Appellant argued that if the government intended to rely on the Lidar III device’s reading to establish probable cause, appellant was entitled to the calibration report in preparation for the hearing. The trial judge asked the government whether it planned to establish probable cause by relying solely on the testimony of the officer’s visual assessment, or whether Officer Reisinger was going to testify to the speed that the Li-dar III device registered upon tracking appellant’s car. The government responded that it intended to “use[] the [L]idar gun to confirm [the officer’s] visual inspection of the [vehicle],” but argued that the actual calibration of the Lidar III device was “irrelevant” to the determination of whether the officer had a good faith basis for pulling over and subsequently arresting appellant. The government did not produce the documents requested.
In an effort to move the trial forward, the judge decided to proceed with the testimony of Officer Reisinger, and explained that she would determine whether proof of calibration was required, based on the officer’s testimony. During the cross-examination of Officer Reisinger, defense counsel elicited much of the information requested in his discovery request, Officer Reisinger: (1) testified he knew that the Lidar III device had been calibrated by a private company six days prior to appellant’s arrest, and relied on that for its accuracy; 4 (2) described his training on the use of the Lidar III device; (3) said he did not take notes on the day of the arrest; and (4) explained that on the day of the arrest, he had conducted the internal *285 self-test recommended by the manufacturer of the Lidar III device.
In light of Officer Reisinger’s reliance on the independent calibration of the Lidar III device, the trial court ordered the government, over the prosecutor’s objection, to produce the requested calibration report. 5 The prosecutor then presented a certificate of accuracy of the Lidar III device’s calibration, and a calibration report with a Pro Laser III “safety touch sheet” from the company that had calibrated the Lidar III device; both documents were dated June 18, 2008, six days before appellant was stopped and arrested for speeding. Because the trial court had allowed Officer Reisinger to testify before the Lidar III device’s calibration documents had been produced to the defense, the trial court explained that if there were questions regarding the documents, appellant’s trial counsel would be permitted to re-cross-examine Officer Reisinger. Counsel declined to do so and did not ask for a continuance to consider and prepare for examination based on the documents newly produced by the government. In short, counsel received the requested calibration documents and had an opportunity to consider and use them at the suppression hearing.
Appellant nonetheless maintains that other requested documents, regarding Officer Reisinger’s training and use of the Lidar III device, were never produced by the government. Appellant does not, however, “demonstrate a relationship between the requested evidence and the issues” relevant to suppression.
Curtis,
III. Suppression of Statements
Appellant claims that two statements he made at the time of arrest were procured in violation of his Miranda rights, and thus, should have been suppressed. The government disagrees, claiming, as the trial court found, that the first statement (“[I]t’s just some weed.”) was admissible *286 under the “public safety” exception to Miranda, while the second statement (“[I] just got it at Riggs Road, it’s for my girl.”) was spontaneous and not made in response to custodial interrogation. The trial court relied on appellant’s statements to find that the substance in appellant’s sock was marijuana, and that he was therefore guilty of attempted possession of marijuana.
The government is constitutionally precluded by the Fifth Amendment’s Self-Incrimination Clause from using in its case-in-chief a defendant’s statement, whether exculpatory or inculpatory, stemming from custodial interrogation unless the defendant has been advised of his right to remain silent and to have an attorney present.
See Miranda,
“Whether, on the duly established facts, [appellant] was subjected to custodial interrogation without the benefit of
Miranda
warnings ... is a question of law that the court reviews
de novo.” Reid v. United States,
A. Public Safety Exception
Appellant challenges the trial court’s determination that his statement in response to the officer’s question (“what’s that?”) during the search was not subject to suppression, given that Officer Reisinger’s question was “a mechanism designed to elicit an incriminating statement from [appellant],” and the officer’s “concern for his safety was misplaced and inappropriately handled.” Appellant claims that there were many other options available to the officer to ensure his safety from, e.g., being stuck by a needle, other than asking him generally about what was in the sock and that “the tactic used by Reisinger was laden with trick and artifice, specifically designed to elicit a statement by appellant.” The government argues that safety concerns justified Officer Reisinger’s inquiry about a suspicious-looking lump in appellant sock.
*287
The question presented for our resolution is whether the narrow “public safety” exception to
Miranda’s
rule of exclusion established in
New York v. Quarles,
The
Quarles
exception applies to questions prompted by concern for public safety,
see Trice v. United States,
The public safety exception applies only where there is “an objectively reasonable need to protect the police or the public from any immediate danger associated with [a] weapon.”
Quarles,
In this case, the trial court found that, based on the totality of the circumstances, Officer Reisinger acted reasonably, out of a concern for his own safety, in inquiring of appellant regarding the bulge in his sock. The court credited Officer Reisinger’s testimony that “[i]n my 12 years, I’ve seen a lot of things — razor blades, knives. So you always want to check to make sure before you grab anything that you know what it is that you’re grabbing.”
Cf. Johnson v. United States,
We have not had occasion to address a situation involving a concern for an officer’s safety over possible injury from needles and sharp objects; our cases to date have concerned only concealed or abandoned guns.
See, e.g., Green v. United States,
But what question could the officer ask that would reasonably protect him from injury, yet be consistent with
Miranda’s,
mandate? The safety excep
*289
tion, we emphasize, is “narrow,”
Quarles,
Viewed in the context of appellant’s arrest and search, Officer Reisinger’s question, asked upon seeing a bulge in appellant’s sock that could conceal a needle or other sharp or harmful object that would
*290
have posed a risk of injury to the officer as he patted down and searched the sock, reflected his “stated aim to ascertain and neutralize any threat” from what he had seen.
Crook v. United States,
Thus, we hold that the trial judge did not err in denying the motion to suppress the first of appellant’s statements (“[I]t’s just some weed.”).
B. Spontaneous Statement
Appellant claims that his second statement about the marijuana, “[I] just got it at Riggs Road, it’s for my girl,” was inadmissible because it was made in response to improper questioning by the officers given that appellant had not been read his Miranda rights. 7
If a suspect is in custody but volunteers a statement — in the absence of interrogation or its equivalent — there is no
Miranda
violation even if the suspect was not advised of his rights.
See Innis,
In this case, the trial court credited Officer Reisinger’s testimony that appellant’s statement about buying the marijuana for his girlfriend was volunteered during the course of the officer’s questioning about “strictly biographical information.” Appellant was not interrogated about why he had the drugs, and it does not seem plausible that the officer would have had any reason to think that asking standard booking questions after the arrest would likely elicit an incriminating response from appellant.
See (Courtney) Johnson v. United States,
For the foregoing reasons, we affirm appellant’s conviction.
So ordered.
Notes
.
Miranda v.
Arizona,
. Appellant was sentenced to 180 days' imprisonment, with execution of sentence suspended as to all but sixty days, one year of *282 supervised probation conditioned on continued drug testing and treatment, and a $50 fine to be paid to the Victims of Violent Crime Compensation Fund.
. At the hearing on the motion to suppress, appellant relied on the Superior Court's opinion in District of Columbia v. Chatilovicz, No. 2006-CTF-2633 (Apr. 30, 2008), which set forth testing procedures (to prove reliability and accuracy of the device) to be followed by the government in order to submit Lidar device test results in court as evidence. Id, at 39. As the trial judge explained, "Judge A[ ]brecht's opinion in Chatilovicz clearly governs the use of this evidence for the specific purpose of providing a sufficient evidentiary basis to convict the defendant of speeding. Not, however, for justifying a traffic stop based on the suspicion of speeding.”
. Counsel asked the officer, "Are you telling the court that you were basing the accuracy of the gun that day on the fact that it had been calibrated recently?” Officer Reisinger responded, "Yeah, once the Lidar guns come back, they’re calibrated, obviously, they’re tested.”
. In
Quarles,
two police officers were approached by a woman who said that she had been raped, and that the rapist entered a nearby supermarket and was carrying gun.
. Appellant's brief argued that the statement was inadmissible because the officers had called appellant’s employer (the D.C. Fire Department) to come to the scene of arrest in order to "promote and elicit discourse” between appellant and his fellow fire department colleagues, which Officer Reisinger then overheard, and the government used to incriminate appellant. Appellant's counsel conceded at oral argument, however, that the record reflects that appellant made the statement prior to the arrival of the Fire Department officials.
