Only under a direct threat would I seek to "off" someone, and I own firearms for that purpose.
I especially favor the Sig-226.
Kind of a remote, if you think about it.
If you had remote with off buttons for 3 different people, what people would they be?
3 wouldn't be enough, and Im not sure I would assign those 3 choices beforehand. Im more of a point and click kinda guy.
#1- that guy who's about to mug me or worse ~ click~
#2- my boss when he's in a sour mood ~ click~ ( I might have more fun with that and change his channel )
#3 my lover ~ just so I can pause it all and make the moment last. Oh ! Replay and often.
