I guess I see quite a few more open carriers than you do, replete with homemade SWAT-ish accessorization, and my strong urge is to leave the local area with no unseemly delay.
I don’t necessarily think they are going to go off any second, but I can see the trend line and don’t want to be anywhere around when it reaches the critical point.
So, they have secured themselves from the danger I pose to them, anyway.
