IN THE REAL world the guy busting into a room has the gun at the ready
Maybe. Or maybe not. I've used a gun in self defence. A man was trying to break into my home. I called the police, then confronted him and told him to leave. When he didn't, I brandished my gun. And then he left. I doubt that's all that unusual. Likely more so than the type of home invasion you describe.
ASK ANY experienced police officer and they will tell you that over 60 percent of guns that wind up on the street are stolen from property crimes
And how would your average police know that? They hardly know the laws they're tasked to enforce. The US ATF has, surprisingly, looked into this. They believe stolen guns account for 1 in 10 guns used in crimes. The largest source is straw purchases. Then corrupt federally licensed gun dealers.
