Hobocop campaign

The Hobocop Campaign is an undercover police campaign in which police disguise themselves as homeless ("hobos") in order to be able to sneak up on suspects and get close enough to search a suspect and then announce themselves as police officers.
Toronto Police applied the campaign to catch distracted drivers talking on cellular telephones.
