Of course, "cutting your own switch" in days gone by probably isn't too much better than a stun-gun.
By the way, as dangerously foolish (read: male) teenagers, my friends and I would use a stun-gun to shock each other. We'd never be able to keep it in place for more than a fraction of a second since the target was always aware that it was coming, so there were never any serious effects. I even used an old one with a weak battery to keep me awake on a Spring Break trip to Florida when my radio was broken.
This is no frog in the pot scenario.
Using a stun gun on an 8 year old is a criminal offense, besides being incredible moronic thing to do
A stun gun in the hands of a police officer using it for control verses a weapon in the hands of a officer makes for a few less dead dump ass "hold muh beer drunks" or dopers and a few less cops putting a slug into a normally harmless idiot who had too much to drink or taken too many drugs to know better.
