Which scenario does NOT qualify as an exception to an arrest warrant?

The scenario that does not qualify as an exception to an arrest warrant is related to charging a minor traffic violation. Generally, law enforcement officers do not have the authority to make an arrest for minor traffic offenses without a warrant. Instead, officers typically issue citations or summonses for such violations.

In contrast, other scenarios mentioned, such as exigent circumstances or hot pursuit, allow for warrantless arrests when immediate action is necessary to prevent harm, destruction of evidence, or to apprehend a suspect who is fleeing. Additionally, if a misdemeanor is committed in the presence of an officer, they have the legal right to make an arrest without a warrant. The plain view doctrine also permits officers to seize evidence or arrest a suspect without a warrant if they observe illegal activity occurring in their immediate sight.

Thus, charging a minor traffic violation stands out as the exception where an officer would normally require a warrant to make an arrest, making it the correct choice for this question.
