You have to be trained in the operation and use of handcuffs,you may think "how hard can they be to use?" i know, but there is training for them and like C3 said, they can be dangerous if used improperly. EXAMPLE: if im a halfway intelligent BG and i see that you are gonna "attempt" to cuff me, i will "let" you apply one cuff then im gonna use the loose cuff as a weapon on you. Also if you are carrying around cuffs and you shoot somebody, it will be brought up in court "against you", and like already stated,you should never be that close to a BG. I just dont reccomend private citizens to carry handcuffs.
