If you are stupid enough (or drugged up enough) to allow yourself to get into a fight with two cops, you are going to be subdued and arrested. In the old days they used a Billy Club or Black Jack, both of which always caused physical injuries, and occasionally fatal injuries. Today, they will use a Taser if they have the opportunity, which very seldom cause physical injuries.
Or would you take the pacifist approach and just allow a guy taking swings at a cop to walk away so that no one gets hurt?
Personally, as a taxpayer I have no problem with cops carrying a $10 Billy Club instead of a $1000 Taser, but I guess the stand-off capabilities of the Taser does save some $s on police worker's comp claims.
Incredibly there are people on this thread who say he got what was coming to him. Many of today's cold-hearted cops probably feel the same way. Like I said resisting arrest should not be a prerequisite to getting tazed to death. And it seems to be happening more and more.
Cops associate their guns with death, unfortunately not so with tasers so they may be too quick to use them unnecessarily. Look for more and more murders at the hands of law enforcement from tasering until they are either sued into oblivion or ruled unconstitutional.
