The authorities must convince the courts that the informant is reliable. Another necessity for issuance of a warrant is the informant’s rationale that has led to conclusion that the suspect is about to commit a crime or is in the process of committing a crime. In the case, Suzan informs the police in California that two suspects are about to transport heroin. The police then inform their counterparts in Chicago.

The general rule is that searches are supposed to be made after a warrant has been issued by a court. There are, however, exemptions to this rule and the police can legally search a personal vehicle without a warrant. Such exemptions include “searches with consent, special need beyond law, exigent circumstances, stop and frisk and motor vehicle” searches (Carmen, 2009, 204).

Further, the actual detection of a suspicious material in the car trunk was an instant event. The police can also argue that it was a stop and frisk exercise since the car driver behaved suspiciously in a deserted area. The law also allows the police to make ...Show more
