You know the funny part? Most of these gunbangers don't even realize that in a home invasion, if their gun isn't right at hand for them to pick up immediately, they'll just get shot while they're going for it.
I'm not even sure they (the gunbangers) understand how fast things move when something like that happens -- you hear the door get kicked in, BANG, and then within a few seconds there are one-to-several people inside with guns out and either giving orders or just shooting people down. And let's not even think about the case when you're asleep and get woken up by the door-kick -- the odds that they'll even know what's happening are so slight that it isn't even funny.
And somehow a gun will save you from this.
If you're worried about home invasions, your #1 priority needs to be to MOVE SOMEWHERE ELSE, because the odds are _always_ heavily in favor of the guy who already has his gun out, and in a home invasion? Guess what, that ain't you.
