I'm not the person you're responding to, but...
If I hear my neighborhood has started to become targeted by people checking houses for unlocked doors and stealing stuff, I think an appropriate response for me is to ensure it is difficult or impossible for me to "inadvertently" leave my own doors unlocked so my stuff doesn't get stolen, and also to encourage or perhaps even enforce[1] my neighbors to ensure their doors are always locked to make this sort of theft impossible and remove the temptation for that sort of crime.
