In most cases you are right when you say that you will be treated like a victim if you act like one, but I wouldn't tie having no weapons to acting like a victim in such a general way.

It just depends on where you live and how people behave in certain situations.

If I lived in the US, I'd probably have a gun at home, because the probability that it will protect my life outweights the chance that someone might get shot accidentally. (for example if you have children at home)

But in many western european countries you have almost no upside by possessing a gun (because you just wont experience a life threatening situation with a burglar), just the downside of your children possibly somehow getting their hands on the gun, no matter how safe you stored it.

Guns are expensive (well, the illegal ones, not the legal, they're not expensive). Most burglars won't use guns. To expensive, way to noisy in a country that is very crowded and is very afraid of guns (I imagine over 100 people phoning the police for the sound of a gunshot) and too high a fine ($ 10.000) and too high a sentence should they get arrested breaking and entering.
