What is the standard of proof for arrest?

• A. Reasonable cause
• B. Probable cause
• C. Reasonable suspicion
• D. Beyond a reasonable doubt

Answer: (A)

Probable cause is the standard of proof for arrest. It requires that the facts and circumstances known to the officer would lead a reasonable person to believe that the suspect has committed, is committing, or is about to commit a crime. This standard applies whether the arrest is made with a warrant (the warrant must be supported by probable cause) or without one (the officer must have probable cause at the time of arrest). Reasonable suspicion is not enough for an arrest; it justifies a stop or brief investigative detention. Beyond a reasonable doubt is the standard for proving guilt at trial, not for making an arrest.
