You want thieves to be armed?

It's much more safe for a law abiding citizen to assume that all thieves are armed, because they most likely are.

Burglars in particular tend to target empty houses precisely to avoid confrontation. To bring a weapon only make sense if there is a chance of getting shot at.

That’s awful, it’s terrible that the thieves fear for their lives so much that they arm themselves

They frequently already are. Even here in Canada[1] where any kind of "carry" is generally not allowed. Shockingly, thieves often don't care about gun laws though.
