Question

Quizplus · Accepted Answer

Before a warrant may be issued, probable cause must be established. This means that there must be sufficient evidence to believe that a crime has been committed and that the person to be arrested is responsible for that crime. The existence of witnesses, evidence, or an informant may all contribute to establishing probable cause, but they are not required in and of themselves. Ultimately, it is up to the judge to determine whether probable cause has been established before issuing a warrant.
