This should have a new title “If my privacy (opsec) has been breached with my neighbors or friends, what to do?”
In a real SHTF you will have to either defend or run at some point whether your neighbors know or not. I would figure out what triggers each scenario. Then plan each with as much detail as possible. Just figure you will be early on the Let Get Jacks Stuff list. And maybe you will need to be proactive if they are threatening your security.
