In which circumstance is an arrest without a warrant permitted?

An arrest without a warrant is permitted when an officer has probable cause to believe that a felony has been committed in a public space. Under the Fourth Amendment, law enforcement officers are granted the authority to make arrests without a warrant when they have sufficient information to reasonably believe that a crime has occurred or is occurring, particularly for felonies. This is justified because having probable cause allows the officer to act swiftly to prevent further criminal activity or ensure public safety.

In public spaces, the expectation of privacy is lower than in private homes, which gives officers more leeway to take immediate action if they identify a suspect connected to a felony. This principle is rooted in both the need for effective law enforcement and the need to protect public safety.

While the other options may seem relevant under specific circumstances, they do not generally align with the standard for warrantless arrests as clearly as the chosen answer does.
