I don't know, I ain't no huge fan of the "law and order" types. But cracking an 80something year old dude in the head with a hammer is pretty fucked up.
This shit blew my mind back in the day, much like how I can plug a dongle into my cigarette lighter and somehow Bluetooth my phone to my old ass stereo.
We have this ridiculous system at my work. Knives are prohibited, but get through all the time, tape measures and water bottles really piss it off though.
It adds flavor.
