You clearly don't know m/any criminals.

They're not all morons hopped on something. Some are cleverer than you would ever want to know about.

So tell me. What car thief is going to be doing any of this, instead of chucking a piece of broken spark plug through a window and driving off with the car 30 seconds later?

I don't know why this thread has converged on car theft as the crime most apposite to this issue; B&E seems like the much more relevant issue.

There is significant potential herd immunity to crimes like B&E stemming from a reputation of a high proportion of armed residents.

It is odd.

Notably, when I did a ride along once, the burglary call we responded too, the officer got a call from his Sergeant and they didn’t put anything over the radio until they already cleared the place.

As to if the perps had cleared out already due to some SDR MAC address magic (good call!) I guess we’ll never know. Everyone just assumed it was a false alarm. /s
