I couldn't agree more. Nobody said the Police were the best trained security personnel in the land. They are literally trained to "shoot first - ask questions later". When responding to a home alarm situation, their adrenalin is pumping hard. They don't have any idea of what they are coming to. Perhaps the cat tripped the alarm, but then again, ten well armed gang bangers might await them. When responding to a home alarm situation, the cops are running on high octane.

I think the OP is proof that poor training and over reacting created this tragedy. However, both you and I can wish all day long that better training programs be implemented to train the police how to better respond to a home break in situation. I, for one, have grown tired of hoping. Long after I am dead and gone from this world, the cops will still be under trained and ill equipped to handle such situations. So, in the mean time, we must deal with the reality of their tendency to over react.

A prudent man would take note of the incoming troops arriving with loaded weapons and stay indoors until the shooting is OVER.

But, as sure as the day is long, there will continue to be those "friendly neighbors" who, upon hearing a home alarm go off, will grab their handy hand gun and walk outside to "check out the situation".
And, as sure as the sun comes up, they may find themselves in the middle of something they weren't planning on.
