First of all I expect that I will be attacked for what I am about to write but...
I carry the most effective weapon the state or city will allow me, yes I have and continue to carry a concealed hand gun (I have a CCW), pepper spray and knives to many scenes with cops on scene also. my life is always going to be worth more then someones who is trying to hurt me, my family or innocent people. Most states self defense/use of force/deadly force laws are simple, you try to hurt someone or commit a violent felony, equal/escalating force may be used to stop it, and guess what? assault of a EMS worker is a violent felony.
No civilian job is worth my life, I would much rather be jobless and alive then dead with full honors at my funeral.
Anyone that thinks that someone could get a hold of my or a cops gun easily never watched or took a weapon retention course, keeping in control of your weapon is not that hard with just class room teaching on how to do so.
