As a general rule, searches conducted without a valid search warrant signed by a judge violate the Fourth Amendment, but like most rules of law, there are a number of explicit exceptions. In fact, most searches occur without warrants because police take advantage of these exceptions to the Fourth Amendment...

Traffic stops typically occur as a result of suspected moving violations committed by the driver of the vehicle. Passengers cannot be held responsible for the driver's conduct and are generally free to leave, unless police become suspicious of them during the course of the stop...

No. We teach people that they have rights, and that these rights are secured by the principal documents that guarantee our civil liberties -- the U.S. Constitution and the Bill of Rights. An informed individual who invokes his constitutional protections is doing exactly what our nation's founders intended. They created these documents to...

Unfortunately, many people get fooled by some version of this commonly used police officer's line: "Everything will be easier if you just cooperate". That's true to some extent -- it will make things much easier for the police officer who's trying to arrest you! -- but when it comes to you consenting to searches and answering incriminating questions, it couldn't be further from the truth...

Yes. Minors generally have the same rights as adults. For example, minors can refuse searches and decline to answer questions without an attorney present. Nevertheless, minors face unique challenges when attempting to exercise these rights...

No. If a police officer asks your permission to search, you are under no obligation to consent. The main reason why officers ask is because they don't have enough evidence to search without your consent. Don't expect an officer to tell you of your right not to consent. Any time you consent to a search request you are naively waiving your constitutional rights.

This is one of those "it depends on the circumstances" questions. Police can obtain consent to search from anyone with control over the property; however any occupant of a residence can refuse consent, even if other occupants agree to a search. Unfortunately, you must be present in order to assert your refusal. The Supreme Court has ruled that...

Simply put, the number of arrests an officer makes is a major factor used to determine his job performance. Police officers know that the easiest way to make arrests is to find people in possession of illegal drugs, so they want to search everyone they can find...

Yes. Police can, will, and often do lie; especially if it helps them make arrests. The rules regarding entrapment usually tip in favor of law-enforcement, so police won't hesitate to trick you into incriminating yourself or others...

College students suffer from an unfortunate lack of privacy rights in many situations. The university owns the dorm, so school officials can often search rooms at their own discretion. College students still have 4th Amendment rights that apply in other situations...

Generally not. The Bill of Rights protections that matter most during police encounters are mandated by the U.S. Constitution as interpreted by the U.S. Supreme Court, and all states are required to follow them. States can offer more protection of these rights, but not less. There are some variations regarding...
