It's touching to see how much faith you put into home intruders.
It's not a matter of faith. It's a matter of gun control.
Even someone who's breaking into homes to steal stuff to sell for drug money knows better than to walk down the street carrying a long gun, and handguns are:
1. Hard to get legitimately, because they're restricted weapons,
2. Hard to get by stealing because: a) there aren't many of them and b) the secure storage requirements for restricted weapons are pretty strict.
3. Expensive to get on the black market (because of #1 and #2).
... so the people who have enough ready cash that they can buy an illicit gun that might be useful in a home invasion are generally not the people so hard up for cash that they'd resort to home invasions.
