So, should we bulldoze homes in case they house thieves?

I specifically said abandoned / derelict. Shall I point you at the wiki page of a "straw man argument"?

I'm not interested in policing thought crimes,just real ones.

And I also mentioned those. Not sure what your goal is here.

I read your message as removing abandoned buildings because they might be used as some sort of gang HQ. Either they are doing illegal things and should be put into the legal system, or they aren't.
