Beside people wanting to rob, steal or even harm, add the people that are crazy on drugs. That's one reason we need to have a stout gun with plenty of rounds. If two or three big policemen can't handle a person in that state, what chance do I have?
I'd say, yes, you did do extremely well there and that let the police do their jobs w/o extra worries of a hyped up home owner trying to take things into his own hands when not necessary. That sounds like a really nerve racking way, even more than normal, for a typical break in. Especially with your family at home.
Who remembers the old saw, "Next time your are being robbed, call a hippy."
