OPINION
{1} Defendant was stopped at a police roadblock and was found to have a breath alcohol content (BAC) of .12. She appeals her conviction for driving while intoxicated (DWI), arguing that police misconduct in failing to charge another intoxicated driver rendered the roadblock unconstitutional. In the alternative, she argues that the police decision to prosecute her but not the other driver violates her right to equal protection under the law. We affirm her convictions.
FACTS
{2} The Albuquerque Police Department (APD) set up a sobriety checkpoint at the intersection of Paseo del Norte and Coors Boulevard on the night of August 5, 2000. Sergeant Murray Conrad proposed the roadblock to his supervisors, who approved the plan. The roadblock plan included procedures that the officers at the roadblock were to follow. The officers were to stop every vehicle and ask a set of scripted questions. If an officer suspected that a driver had been drinking, the driver was referred to the secondary inspection area for sobriety testing. A person who showed signs of intoxication was directed to the “BATmobile” for a breathalyzer test.
{3} When Defendant stopped at the roadblock, she was subjected to sobriety testing, then a breathalyzer test. Her BAC was recorded at .12, .04 above the legal limit of .08. See NMSA 1978, § 66-8-110(0) (1993). She was charged with DWI, booked, and prosecuted.
{4} One of the other drivers stopped at the same roadblock turned out to be the brother of an APD officer (hereinafter “Brother”). Brother was given a breathalyzer test and found to have a BAC of .09. Rather than charging Brother with DWI, however, Sergeant Conrad told another officer to give Brother a ride home. Sergeant Conrad acknowledged that in doing so he violated police procedures. He was later reprimanded by APD and temporarily suspended from working with the DWI squad.
{5} Defendant was tried in Metropolitan Court. She moved to suppress all evidence against her and dismiss the charges, arguing that the favorable treatment of Brother rendered the roadblock unconstitutional. The trial court denied her motion, and she was convicted of DWI. Defendant appealed to the district court, which affirmed her conviction. She now appeals to this Court.
DISCUSSION
The Failure to Charge One Intoxicated Individual Did Not Render the Roadblock Unconstitutional
{6} “[Sjtopping motorists for the purpose of detecting and apprehending drunk drivers constitutes a ‘seizure’ under the fourth amendment.” City of Las Cruces v. Betancourt,
{7} In Betancourt, this Court held that the police must implement uniform procedures at roadblocks as a means to restrict the discretion of field officers. Id. at 658-59,
{8} Defendant argues that her arrest was unconstitutional because the police failed to follow uniform procedures at the roadblock in question when they released one intoxicated driver while charging others with DWI. We agree with the State, however, that the Betancourt analysis determines the constitutionality of a roadblock stop, and not later police actions. The argument in Betancourt focused on whether the drivers’ constitutional rights were infringed when they were stopped at the roadblock in question. Id. at 657,
{9} Defendant does not assert that the officers at the roadblock in question failed to follow uniform procedures in stopping vehicles. Defendant argues that because roadblocks present an exception to the reasonable suspicion requirement, any aberration should be cause to invalidate roadblock stops. She argues that, unless we extend the requirement of uniformity to later stages of the roadblock, we will give police departments “a blank check ... for anything that occurs after a car pulls up to an orange cone.”
? That is not the case. Each action after the initial stop is subject to judicial scrutiny. See State v. Goss,
{11} Nor have any subsequent cases analyzing roadblocks extended the Betancourt analysis beyond the initial stop of the vehicle. Instead, we have the reasonableness requirement for roadblocks as providing “a constitutionally adequate substitute for the reasonable suspicion that would otherwise by required to justify the detention of vehicles and the questioning of their occupants.” Bates,
{12} Defendant cites some out-of-state authority to support her argument that any deviation from the written roadblock plan will render all stops at that roadblock unconstitutional. For example, a Massachusetts court held that it was unconstitutional to extend the hours for a roadblock without supervisory approval. See Commonwealth v. Anderson,
{13} Defendant’s argument that irregularities in post-stop procedures invalidates the roadblock itself is misguided. If a roadblock is unreasonable, then each stop made at that roadblock will be unconstitutional. See generally Betancourt,
{14} We understand Defendant to argue that the release of Brother was part and parcel of the officers’ discretion at this roadblock, and that the discretionary decision to release him violated the core Betancourt principle that discretion be restricted. We disagree with this argument because Sergeant Conrad ultimately testified that he did not have official discretion to release drunk drivers and that he was disciplined for doing so. Thus, we cannot say that this case involves any unconstitutional exercise of discretion. It does involve wrongdoing by the officers at the roadblock. But that wrongdoing had no impact on Defendant’s stop, arrest, test, or conviction.
{15} Defendant concedes that the police followed constitutional guidelines in stopping her vehicle. She raises no argument regarding the grounds for her subsequent detention or arrest. We hold that there was no violation of Defendant’s right to be free from unreasonable searches and seizures.
The Failure to Charge One Intoxicated Individual Did Not Violate Equal Protection
{16} Defendant next argues that the police officers at the scene violated her right to equal protection of the laws when they charged her, but did not charge Brother. We read this argument as a claim of selective prosecution. To establish a claim of selective prosecution, a defendant must prove both a discriminatory effect and a discriminatory purpose. State v. Estrada,
{17} Defendant recognizes that this case is the inverse of a typical selective prosecution ease, where one person is prosecuted even though many others committed the same offense. See, e.g., State v. Cochran,
{18} Even if we accepted Defendant’s argument that the failure to charge Brother constituted a discriminatory effect, we do not agree that the police officers had a discriminatory purpose in charging Defendant with DWI. Defendant presented no evidence showing that the police had an invidious reason for charging her with DWI. She does not claim that the decision to charge her was based on her race, religion, or her attempt to exercise constitutional rights. Instead, Defendant asserts that she was charged because she was not related to an APD officer. We do not agree that this constitutes a discriminatory purpose on the part of the arresting officers. Defendant presented no evidence showing that she was charged with DWI for any reason other than the simple fact that her BAC was above the legal limit. The officers’ reasons for failing to charge Brother do not alter the reasons for charging other drivers, including Defendant, who were in fact driving while intoxicated. Even if the alleged discrimination in this case did not occur — if Brother had been charged with DWI Defendant would still have faced DWI charges. We hold that there was no violation of Defendant’s right to equal protection.
CONCLUSION
{19} We affirm Defendant’s conviction for DWI.
{20} IT IS SO ORDERED.
