I've seen the aftermath of a gang "drive up house hit" windows go down and AK's/ARs empty several magazines into a house--they are usually after someone specifically but don't really care if anyone else home is hit or killed. Impressive Swiss cheese approach. That's why I'll always have a loaded AR within reach in addition to a high capacity pistol. Shotguns are good too. It all depends on where you live I guess.
This is why I have easy access to multiple loaded rifles on top of my SD/HD guns. I live with hurricanes, tornadoes and bad storms. I don't need a looter mob coming by too starved or greedy to care about me and mine. Go without power for a few days and you'll see what I mean. Back in the day, we had looting problems and a lot of home invasions.
