Joey, while your argument has valid points and is well worded, you are missing the big picture, which is that no matter how well you plan, how polite you are, how observant you may be, there are always going to be people out there who are motivated enough and smart enough to mitigate your preparedness and pose a threat to you. And to say that being prepared for that eventuality is somehow wrong headed is naive at best.
Now, I'm not advocating having EMS personnel geared up like they're going on patrol in Afghanistan, but having the means to protect yourself, your crew and your patients is not only a right, it is and ought to be our responsibility.
And the argument about getting your gun taken away and used against you is a red herring. It is old fear based rhetoric espoused by the anti-gun crowd and is patently false. That's like saying " I hope nobody steals your car and runs you over with it." Could it happen? Yeah, sure. But it is so astronomically unlikely as to be almost unheard of.
My whole philosophy on carrying on duty is pretty simple. It comes down to one question, would you rather lose your job or your life?
