Of course. But there are always a few in every country who feel that, given the chance, they could do it better.

True story:

After the theater shootings in Colorado I happened to be in a gun store and overheard two young men each stating flatly that "if I had been there things would have been different." After ten or so repetitions of this I inquired about their training the handle such a situation and was told that no, neither was police trained or had been in the military. Speaking from personal experience I told them that they had no way of knowing how they would react to what would essentially be combat and being untrained they would most likely freeze and/or poop their pants.

This was not well received. They told me that they "had played plenty of paintball" and knew how to handle themselves. I calmly replied that paintball was a game and they weren't likely to die doing it. I was told that "paintball really stings when you get hit." I asked them if they knew of anyone who had been killed by a paintball, and pointed out that an active shooter is active, trying to kill you, and panic would rule them and everyone else.

I think I made my point.

Police and military have to make nanosecond decisions and they have to be the right decision. Is it a gun? Is it a REAL gun? Is there actually a threat here? Do I have a clear field of fire if I must fire? What is behind me, to the sides, up above that I might hit if I miss the bad guy? What will my family do if I'm shot? Maybe...is that just a stick? Okay, he's armed with a knife, not a gun, and now what do I do? He's breaking car windows and he's thrown that old man to the sidewalk -- should I shoot or not?

I have no sympathy for cops who gun down the unarmed or empty their pistols into a suspect who's down. I have no sympathy for a cop or anyone else who uses more force than is necessary. I wish shooting was confined to targets at shooting ranges. I wish that the US had rational gun control laws, made with thought during calm instead of in reaction to another "incident." I wish that the gun culture of the US wasn't so embedded in the national pysche that a gun is looked at as the tool it is.

Mostly, I wish there wasn't evil and greed and such things in the world.
