Hawkeye,
Again I have to agree with you. I saw this take-down on TV an what people must not understand is that a person with a knife can , from a distance of 10' away, lunge and striike in about a second. That is not a lot of time to react. The fact that the officer with a tazer being a couple of blocks away means little. How many times have you seen on "Cops" other similar shows, that perps are repeatedly tazered and still don't go down? I think this was a "righteous shooting" on the part of the police.
