I posted something similar to this on the Legion forums, but I wanted to post something here too.
Frankly, I'm rather upset and disappointed by how much this debate has turned into a personal attack. Just speaking for myself, I know if I had moved to the area or whatnot, I might have gone through similar steps to see what exactly the local firearm laws were and to seek an exception based on precedent for the Legion members.
Now, were some mistakes made? Probably, but "To err is to be human, forgiveness divine"
It's a terrible situation, but to be honest, it was inevitable. The local members knew the laws and knew that they were openly breaking them. All it would have taken was one phone call from an overly nervous or paranoid person, and they would've been in the same situation.
