I kind of like watching people get tased. Here's a video of someone from Popular Mechanics testing the effects of a model called the C2, which shoots CO2-propelled barbs, allowing the tasing to be done from a distance. It doesn't look so bad. I'd probably let them tase me for, say, $75. How much money would you require?
This story also discusses the idea, promulgated by the UN, that tasing constitutes torture. They make the valid point that the alternatives for a criminal, namely being shot or whacked with a baton, are much worse, and that the UN should find something else to worry about. Being the UN, of course, it won't actually do anything, so we needn't be too worried.
