OPINION
John Davis, Jr. appeals his conviction for possession of a controlled substance, cocaine, in an amount less than twenty-eight grams. On appeal, Davis complains of the denial of his motion for a court-appointed expert witness; the admission of evidence allegedly seized in violation of his constitutional rights; error in the charge to the jury; and the punishment assessed by the jury. We find no reversible error and affirm.
At approximately 9:00 p.m. on the night of January 22, 1993, officers McCarver and Gladden of the Texarkana Police Department were patrolling in an unmarked car in a residential area of Texarkana, Texas. McCarver noticed two men standing in the front yard of a residence and recognized Davis as one of the men. The officers drove past the residence, turned the next corner, and drove around the block to return to the residence. McCarver testified that, as the patrol car pulled up to the residence, Davis waved and approached the ear. McCarver rolled down his window. Davis immediately recognized McCarver and turned to walk toward the residence. McCarver ordered Davis to stop, but Davis did not obey the order.
Gladden and McCarver got out of the patrol car and followed Davis to the front porch of the residence. Davis reached the front door of the residence, and McCarver again ordered him to stop. Davis turned and spoke to McCarver. As Davis spoke, McCar-ver saw a clear cellophane baggie in his mouth, but could not see the contents of the baggie. McCarver grabbed Davis in a “bear hug.” As the struggle continued, Sergeant McElhaney, a backup officer, arrived and sprayed Davis with mace.
McCarver had pinned Davis’s arms to his sides. Davis lifted one hand slightly, spit the baggie into his left hand, and threw it toward the front door. Gladden seized the baggie. After Davis was subdued and handcuffed, McCarver inspected the baggie and observed that it contained a white rock-like substance, identified as 2.51 grams of cocaine in a subsequent chemical analysis.
*659 A jury convicted Davis of possession of a controlled substance and sentenced him to ninety-nine years’ confinement.
COURT-APPOINTED EXPERT
Davis complains of the trial court’s denial of his motion for a court-appointed expert to analyze the outside surface of the baggie for traces of saliva.
See
Tex.Code CRIM-PROcAnn. art. 26.05(a) (Vernon 1989) (providing for payment for expert defense ■witnesses). Fundamental fairness entitles indigent defendants to an adequate opportunity to present their claims fairly within the adversarial system.
Ake v. Oklahoma,
The necessity for the appointment depends on whether the defendant has made a sufficient threshold showing of need for the expertise in his particular case.
Rey,
The first factor articulated in
Ake
favors Davis’s position. The private interest in the accuracy of a criminal proceeding is compelling and weighs heavily in the analysis.
Ake,
As for the state or governmental interest, the Supreme Court has interpreted this narrowly and as a matter of economy only.
Id.
at 79,
It is the third factor to which the Supreme Court devoted its analysis and to which Davis devotes his argument. This third factor requires a preliminary showing by the defendant that the issue for which he seeks expert assistance is likely to be a significant factor at trial.
See id.
at 83,
Davis wanted a forensic pathology laboratory in Dallas to test the baggie to determine if it had been in his mouth. The State maintained that the requested testing would not affect any ultimate issue in the case because it is the possession of the contraband, which McCarver saw Davis throw onto the porch, that is the determinative issue.
*660
There is no evidence, in the form of affidavits or sworn testimony, about the capabilities of the testing facility or the potential results that could be obtained from analyzing the baggie to establish that the requested appointment of an expert could support Davis’s defensive theory. Defense counsel is obligated to inform himself about the specific scientific area in question and to provide the court with as much information as possible concerning the usefulness of the requested expert to the defense’s case.

MOTION TO SUPPRESS
Davis contends that the trial court erred in overruling his motion to suppress and in admitting evidence seized in violation of his rights under the federal and state constitutions and the Code of Criminal Procedure.
See
U.S. Const. amend. IV; Tex. Const. art. I, § 9; Tex.Code CRIM.Proc.Ann. art. 1.06 (Vernon 1977), art. 38.28 (Vernon Supp.1995). The trial court denied the motion to suppress after finding that there were material fact issues that should be submitted to the jury. Davis has raised his complaints under both the federal and state constitutions and, therefore, this court analyzes his complaints separately.
See Heitman v. State,
At a suppression hearing, the trial court is the sole judge of the credibility of the witnesses and of the weight to be given their testimony.
Cantu v. State,
Davis has divided his argument into three parts: (1) the lack of reasonable suspicion to support a temporary detention; (2) the war-rantless entry upon his curtilage; and (3) his warrantless arrest. Each of his arguments will be addressed in turn.
A. Temporary Detention
Davis argues that the officers lacked the reasonable suspicion necessary to support a temporary detention under
Terry v. Ohio,
Davis contends that his detention began when MeCarver ordered him to stop. For purposes of the Fourth Amendment, a person is seized if he submits to a show of authority or has been restrained by means of physical force.
California v. Hodari D.,
Davis did not submit to the order to stop; instead, he turned and walked away from the car and from the officers. The earliest point in time at which it could be said *661 Davis was detained was when he turned around on his front porch and faced the officers.
Regardless of when a detention begins, not all temporary detentions are objectionable. A law enforcement officer may stop and briefly detain persons suspected of criminal activity on less information than is constitutionally required for probable cause to arrest.
Terry,
McCarver listed a number of factors that led him to stop Davis: (1) the officers were patrolling in a high-crime area; (2) the officers were patrolling after dark, during peak criminal activity hours; (3) Davis attempted to “flag down” the officers when they drove by in their unmarked car and again “flagged down” the officers after they circled the block and returned; (4) upon approaching the vehicle, Davis recognized McCarver and turned away from the car; and (5) Davis did not heed McCarver’s order to stop. Conversely, Trent Hampton, who was standing in the yard with Davis when the police drove by, denied that Davis approached the officers’ car. Hampton said Davis was going into the house to get a pair of shoes. Hampton also testified that he saw nothing in Davis’s mouth during the time he and Davis were talking, but admitted that he went to his vehicle to get identification when the police arrived and did not see what happened on the porch. The trial court itself noted that Davis could have put the contraband in his mouth later.
McCarver testified that drug dealers frequently flag down and approach unfamiliar cars.
See, e.g., Sanders v. State,
Taken together, the factors listed by McCarver are sufficient to create a reasonable suspicion, which justified temporarily detaining Davis in an effort to obtain further information in accordance with the federal and state constitutions and state law.
B. Warrantless Entry On Curtilage
Davis complains that the officers unlawfully entered the curtilage of his residence because they lacked probable cause to be on the premises. McCarver followed Davis to the front porch of the residence. Davis turned and opened his mouth to speak, revealing the cellophane baggie.
Davis contends that the officer’s intrusion was improper and therefore taints the officer’s observation of the baggie.
See Texas v. Brown,
It is axiomatic that a law enforcement officer has the same right as any common citizen to walk up to and knock on the front door of a residence with the honest intent of asking questions of the occupant. See
Cornealius v. State,
Davis was not inside his residence. He had retreated only to his front porch and was still exposed to public view. McCarver was lawfully on the premises when he saw the baggie in Davis’s mouth.
C. Warrantless Arrest
Davis contends that McCarver lacked probable cause to make a warrantless arrest for possession of a controlled substance because the incriminating nature of the baggie was not immediately apparent. After being unable to open the front door of the house, Davis turned and told the officers that it was his house. As he made this comment, McCarver, who was within ten feet of Davis and had his flashlight beam focused on Davis, saw the baggie in Davis’s mouth. Davis attempted to swallow the baggie, so McCar-ver stepped onto the porch and grabbed Davis. A commotion broke out on the front porch because people inside the house were trying to pull Davis into the house. Arriving officers used mace to subdue Davis. During the confusion, Davis spit out the baggie and threw it into a comer of the porch.
In Texas, warrantless arrests are authorized in limited circumstances. A police officer may arrest an individual without a warrant only if the arrest falls within one of specified exceptions and there is probable cause with respect to that individual.
Stull v. State,
Probable cause for arrest exists when the facts and circumstances within the officer’s knowledge at the time of the arrest and of which he has reasonably trustworthy information are sufficient to warrant a prudent person’s belief that a particular individual had committed or was committing an offense.
See Amores v. State,
In addition to the circumstances already discussed that gave rise to MeCarver’s reasonable suspicion that Davis was involved in criminal activity — including the high-crime area, Davis’s behavior in flagging down the occupants of an unfamiliar car, and his subsequent uncooperative attitude — McCarver had the additional factor of the baggie to consider. McCarver testified that cocaine is commonly stored in baggies and that it is not unusual for an individual to store a baggie of cocaine in his mouth. He also testified that it is common for an individual to swallow or attempt to swallow a baggie containing a controlled substance in an effort to destroy evidence and prevent an arrest. MeCarver’s knowledge as a result of his training and experience as a police officer gives meaning to the baggie he observed in Davis’s mouth.
Probable cause is a flexible, common-sense standard.
Brown,
*663
In
Boyd v. State,
Under the totality of the circumstances, probable cause existed to justify a reasonable person’s belief that Davis was in possession of a controlled substance at the time of his arrest. The drug evidence was not seized pursuant to an unlawful warrantless arrest. The trial court did not abuse its discretion in denying the motion to suppress the drug evidence and admitting that evidence at trial.
CHARGING ERROR
Davis contends that the trial court erroneously charged the jury under Article 38.23(a) of the Code of Criminal Procedure, which reads:
No evidence obtained by an officer or other person in violation of any provisions of the Constitution or laws of the State of Texas, or of the Constitution or laws of the United States of America, shall be admitted in evidence against the accused on the trial of any criminal case.
In any case where the legal evidence raises an issue hereunder, the jury shall be instructed that if it believes, or has a reasonable doubt, that the evidence was obtained in violation of the provisions of this Article, then and in such event, the jury shall disregard any such evidence so obtained.
TexUode CRIM.PROcAnn. art. 38.23(a) (Vernon Supp.1995).
When a fact issue is raised concerning an officer’s reasonable suspicion or the existence of probable cause, the defendant has a statutory right to have the jury charged on the issue.
See Stone v. State,
You are further instructed that if you believe, or have a reasonable doubt that evidence was obtain (sic) by any law enforcement officer in violation of the Constitution or laws of the State of Texas, or of the Constitution or laws of the United States of America, then in such event the jury shall disregard any such evidence so obtained.
Although the State urges that this instruction is adequate, Davis contends that it is incomplete because it lacks the appropriate application paragraphs that would have instructed the jury on the correct mandatory application of the facts to the law of reasonable suspicion for purposes of an investigative detention and the law of probable cause for warrantless entry and warrantless arrest.
The trial court is to provide the jury with both abstract statements of the applicable law and must also apply the law to the evidence in the case.
Riley v. State,
In the present case, the instruction given consists only of an abstract proposition of law drawn directly from article 38.23. The charge does not instruct the jury on the law governing reasonable suspicion or probable cause. The charge does not apply these legal concepts to the evidence presented, nor does it ask the jury to resolve the disputed fact issues that either justify or invalidate the officers’ conduct. Id. The charge is defective.
A finding of error does not end, but rather begins this court’s inquiry.
Almanza v. State,
When a charging error is unpre-served for purposes of appeal, the accused ■will obtain a reversal only if the error is so egregious that he was deprived of a fair and impartial trial.
Almanza,
PUNISHMENT
Davis asserts that the ninety-nine-year sentence assessed by the jury is grossly disproportionate to the offense committed, in violation of his constitutional rights under the Eighth Amendment of the United States Constitution and Article I, Section 13 of the Texas Constitution. Although Davis raises both federal and state constitutional claims, he cites no authority that would require this court to analyze the two claims differently; therefore, his claims will be addressed together.
See Heitman,
The legislature is vested with the power to define crimes and prescribe penalties.
See State ex rel. Smith v. Blackwell,
Davis asks this court to perform the three-part test set out in
Solem v. Helm,
It is questionable whether this test is still viable since the Supreme Court rendered its opinion in
Harmelin v. Michigan,
*665 Even assuming the test is still viable, however, there is no evidence in the appellate record before this court of the sentences imposed on criminals in Texas or other jurisdictions who committed a similar offense. Moreover, in evaluating the gravity of the offense and harshness of the penalty, Davis does not take into consideration that the jury found he had a 1990 conviction for delivery of a controlled substance and a 1990 conviction for possession of a controlled substance. The punishment assessed falls within the permissible range, and when viewed in light of Davis’s criminal history, is not grossly disproportionate to the offense he committed.
Davis also contends that the punishment assessed violates section 311.031(b) of the Texas Government Code. See TexGov’t Code Ann. § 311.081(b) (Vernon 1988). Davis was arrested on January 22, 1993. At that time, possession of cocaine was classified as a felony of the second degree. See Act of May 18, 1989, 71st Leg., R.S., ch. 678, § 1, 1989 Tex.Gen.Laws 2230, 2936, amended by Act of May 29,1993, 73rd Leg., R.S., ch. 900, § 2.02, 1993 Tex.Gen.Laws 3586, 3706. Effective September 1, 1994, however, the Texas Legislature amended the Health and Safety Code and reduced the offense of possession of cocaine in an amount of one gram or more, but less than four grams, to a third degree felony. See Tex.Health & Safety Code Ann. § 481.115 (Vernon Supp.1995).
Davis relies on section 311.031(b) of the Texas Government Code, which provides:
If the penalty, forfeiture, or punishment for any offense is reduced by a reenactment, revision, or amendment of a statute, the penalty, forfeiture, or punishment, if not already imposed, shall be imposed according to the statute as amended.
Tex.Gov’t Code Ann. § 311.031(b). Davis was not tried, convicted, or sentenced until October 1994 and argues that he therefore falls within the revised provisions of the Health and Safety Code.
Davis fails to note that the same Senate bill that amended the Health and Safety Code specifically provides:
(a) The change in law made by this article applies only to an offense committed on or after the effective date of this article. For purposes of this section, an offense is committed before the effective date of this article if any element of the offense occurs before the effective date.
(b) An offense committed before the effective date of this article is covered by the law in effect when the offense was committed, and the former law is continued in effect for that purpose.
Act of May 29, 1993, 73rd Leg., eh. 900, § 2.08, 1993 Tex.Gen.Laws 3714. Section 2.08 of the bill is a specific saving provision. Section 311.031(b) of the Texas Government Code is a general saving provision. Therefore, section 2.08 prevails over the Government Code.
See Ex parte Mangrum,
The trial court did not err in charging the jury on the permissible range of punishment under the law in effect at the time Davis committed the offense.
We affirm the trial court’s judgment.
Notes
.
Compare the present case with the facts in
Rey,
where the defendant relied upon an affidavit supplied by the pathologist the defendant sought to have appointed to his case. Assertions in the affidavit cast doubt on the reliability of the pathology report prepared by the state’s expert.
