I'd like to reply to a few of the comments and misconceptions that I've seen in this thread from a law enforcement officer's perspective.
1) The use of a Taser is not a form of punishment. It is an approved form of controling a non-compliant subject, which is exactly what they were dealing with. We don't use any of the of the tools available to us for punishment, but rather to acheive compliance and/or stop a threat. This guy will get his punishment when he goes in front of a judge.
2) For those who have posted about the Taser being equivalent to deadly force: I'll be blunt...that is total BS. How many people have died after being tased? Of those who have, how many were in good health prior to being tased? Any control techniques that we use above verbal commands come with a extremely slim chance of fatality. For example, if I opt not to use my Taser, but instead us a hands-on takedown of a fleeing subject, he could suffer any number of injuries that could somehow be fatal. While not likely, there is always that possibilty, but hands on techniques are not considered deadly force so why should a Taser. Beleive it or not, the subject is a lot less likely to be injured when tased than if it gets into a hands on situation, or worse yet, the use of a baton. Once the voltage is off, the subject will be left with only some muscle soreness and whatever bumps and scrapes he got from his fall.
3) From a policy perspective, most departments, including mine, allow the use of a Taser to stop a fleeing subject. I would be willing to bet that the officer was operating well within his department's policy.
4) Finally, the most important thing to us when we're out there is officer safety. I want to go home at the end of my shift in the same condition in which I left that morning. The taser, in most situations is hands down the safer option for an officer, as it allows us to gain control while minimizing the risk of having to get too close to the subject. It becomes much more dangerous when we go hands on with a subject. Even if he doesn't have a knife or gun concealed, if he chooses to fight we're still likely to suffer some sort of an injury in the process.
Just some input from a cop for you guys to chew on. Do with it what you will.
