(1) In the US legal system, arrests are made after enough evidence is collected to establish probable cause. Arrests are made with or without a warrant, but there must always be probable cause to arrest. A criminal defendant is usually searched at the time of the arrest. At the police station the defendant is "booked". The booking process involves finger printing and photographing the defendant. Background information on the defendant such as name, address, phone number, and so forth is also collected. (2) The defendant is searched again before he or she is placed in a jail cell. If the defendant's offense is minor, he or she may be allowed to post bail and appear before the judge at a later date.
