Vulnerable to antis - yes, and most of them live in the Burlington area.
I didn't want to just call a dispatcher and ask, but did get hold of a good friend at Burlington PD, and was told that the only local ordinance was that CCW is illegal in the municipal parks, like in front of City Hall. Of course these are centers of much drug activity as well. Additionally, there are some state-owned areas where you cannot carry period, such as courthouses.
The guy who was hassled, hmmm. Two incidents come to mind. First, when Bill C. was in town a couple years back, the USSS closed off Church St., the big pedestrian- only shopper's paradise, and set up metal detectors. It is legal to carry there, but apparently they weren't taking any chances. Some guy realized this, and went home, got his piece, and tried to walk through, and was of course, caught. Don't believe he got it back, either.
The second was a "man with gun" call to the same area, coincidentally, and the police found some clown with his iron tucked in waistband. They simply suggested that he may wish to get a proper holster - LOL.
Anyway, I am still checking into the other cities, and will post info as soon as I get it.
