I don't think they should be barred from being armed but they should have training if they are going to be in a quasi-police role.
I don't think they should be armed. They're supposed to report to the police, that is it. So why do they need a weapon.
Martin clearly screwed up by assaulting Zimmerman and the ambush makes it justifiable homicide, at least that is what the police think.
But if Zimmerman didn't have a weapon it would have just been a guy assaulted and nobody dead.
