Most cops are generally good people. Not all of them, though. Some are flat out power hungry freaks that are only working in the job because it gives them authority over others. Case in point: 72 year old great-grandmother getting a taser in the chest. Yeah, she was certainly a threat and a clear and present danger. This dude needs to get fired. No excuses and no second chances. If something in his brain rationalizes how this is an OK thing, then he is not fit to be in a uniform. Click through.
Note that I think the taser — and other non-lethal options — are great tools for law enforcement (and private citizens) to have in their bag ‘o tools. The wielder of the tool, though, needs to realize that the line for using it is still pretty far down the road.
