United States v. Cooper

Plain English (For Everyone)

Police searched a car because the driver was acting suspiciously and the officer smelled marijuana. The court agreed this was legal because the driver's actions and the smell together gave the police a good reason to believe there was evidence of a crime inside. The evidence found was allowed to be used in court.

For Legal Practitioners

The Second Circuit affirmed the denial of a motion to suppress, holding that probable cause for a warrantless vehicle search existed based on the totality of the circumstances. The court found that the defendant's furtive movements, coupled with the distinct odor of marijuana, created a fair probability of contraband, satisfying the Fourth Amendment standard.

For Law Students

This case illustrates the application of the 'totality of the circumstances' test for probable cause in vehicle searches.

Scenario: You are pulled over by police and the officer claims they smell marijuana and notices you reaching around in your car. The officer then searches your vehicle.

Your Rights: You have the right to not have your vehicle searched without probable cause. However, the smell of marijuana and furtive movements can be considered by the court as contributing factors to probable cause.

What To Do: Do not physically resist the search, but clearly state that you do not consent to the search. Remember the details of the stop, including what the officer said and did. Contact a lawyer as soon as possible to discuss whether the search was lawful.

Is it legal for police to search my car if they smell marijuana?

This ruling applies to federal law and the Second Circuit's interpretation of the Fourth Amendment. State laws regarding marijuana and probable cause may vary.

For Individuals suspected of drug offenses
