The legal definition of a “switch blade knife” is rather inexact, and varies greatly from jurisdiction to jurisdiction.
Ability to extend the blade with only one hand is the definition in many places.
Arresting a convicted felon out on parole with a probable illegal weapon is EXACTLY the right thing for a patrolman to do. The judge and prosecutor determine guilt or innocence, NOT the patrolman.
“Probable” illegal weapon? Are you trying to tell me that the 6 cops didn’t know Baltimore’s definition of a switchblade?
