I could think of half a dozen ways I could take on a burglar without resorting to a gun. But the reality is they would probably run away once they realized someone was home and the cops had been called.
Actually, burglary statistics are about the same in European countries were guns are banned. Because you break into a house where someone is home, you are more likely to be identified and prosecuted.
Now, when I lived in Cicero (Good times), I was robbed while I was out on National Guard maneuvers The Cicero cops just wrote up a report and that was the end of it. No investigation, no dusting for prints, etc.
Had I been home, and been able to identify the perps, or if there had been some kind of confrontation they'd have taken it more seriously, I'm sure. That's why burglars don't break into homes, it increases their chances of being caught.
Only about 100 people are killed in the course of a burglary each year, and less than 200 homicides are ruled as justified self-defense (most of those domestic, not home invasion).
