Good to hear your crew and company made it through unscathed.
Without a concealed carry law, carrying one in your vehicle is the next best thing IMHO. Sucks they won't let you guys carry.
Common sense indicates anything that needs protecting is protected with a firearm, bank, armored truck, President, every federal and government building, cockpit, politician security detail, etc. Mayor Bloomberg, doesn't hide his anti-gun agenda, yet is protected with guys private security with firearms constantly. The irony is sickening.
Laws don't and regulations don't stop crime, they might deter those on the fence of committing one, but don't stop it. Criminals don't care about laws, they are lawless, thus they don't care if they're breaking one or four laws. Once they've made a decision to break the law, laws won't stop them, only more force or a more efficient use of force will stop them, usually another firearm.
