I've worked as a cashier and counter person for many years. I've gotton to know many law enforcement people. They are human, like everyone else. They have a difficult job as well as an unpopular job, then they have to go home to their spouse and kids and moms and dads and the rest and try to behave appropriatly, even though they are vilified daily and need to confront armed perpetrators as a part of getting paid to support themselves and their family. I think it is an essential job, in todays world.

They will not attack you, without cause. If you aren't a threat to yourself or anyone else, they will not confront you, nor attack you or detain you. I've known a good number of them, they seem reasonable and friendly to me. If they do think your an immediate threat to yourself or anyone else, they will act appropriate to the situation, with what tools they have to use. I know they can't use deadly force unless it is a last resort to avoid innocent people from becoming injured or killed. I'm not sure of the laws on flak jackets, or bullet proof vests, but I doubt they are "that" illegal, if they are, in fact, illegal. That would not be a crime that would require deadly force, if you just wore a flak jacket. I'm not sure about that word. Well, bullet proof vest. If you ask me, my advice is it is safe to wear it in public. If it is illegal, they should just tell you and, most likey, give you a warning. They might confiscate it, but I doubt it. Your good. Feel free. carry on. have a good time.
