Under warrantless arrest rules, peace officers may arrest without a warrant when there is probable cause to believe a felony has occurred.

• A. It may be done only if the felony occurred within the officer's jurisdiction.
• B. It may be done when there is probable cause to believe a felony has occurred.
• C. It may be done only with an arrest warrant.
• D. It may be done only if the felony occurred in the officer's presence.

Answer: (B)

The main idea is that for felonies, officers can arrest without a warrant if they have probable cause to believe the felony has occurred. The key point is that witnessing the crime is not required, and a warrant isn’t necessary when there’s probable cause to believe a felony was committed. This means the arrest can be made based on that probable cause even if the officer didn’t see the offense and even if it happened outside the officer’s immediate presence or jurisdiction. The other restrictions—requiring the crime to have occurred within the officer’s jurisdiction, requiring the officer to witness the crime, or requiring an arrest warrant—do not apply to this rule.
