The United States Constitution provides that its citizens are not to be subjected to unreasonable searches and seizures. This means that, under most circumstances, your residence, your car, your personal effects, and your person are not subject to search unless you give your consent. However, exceptions are made for searches which are done after a search warrant has been issued. Court decisions have also opened the door for other searches where special circumstances exist at the time of the search. Also, a search of your person and an inventory of personal property in your possession is normally permitted after you have been arrested.
If you are detained by a law enforcement officer and are asked to permit a search, you may indicate that you do not consent to the search, whether or not you believe the search is legally permissible. It is appropriate to make note of the officer's name and badge number, and you should try to remember the details of the incident, as this information may later be helpful in deciding whether or not you should have been arrested or whether evidence was properly obtained.
It is a violation of Arizona law to provide false information to a police officer and/or to obstruct an officer in the performance of his/her duties. Therefore, you should always provide identification if an officer requests it. If you are driving a car and are stopped, you will be expected to be able to provide your driver's license, vehicle registration, and proof of insurance. Also, case law has established that your car may be searched without a warrant, if an officer has probable cause. To preserve your rights, you may clearly state that you do not consent to a search.
