Really? They think open carry needs to be met with drawn guns?
Since when the hell has any felon and/or gangbanger carried a gun out in the open, outside of the commission of a crime using that firearm? I've never heard of a case! However, it doesn't mean it hasn't happened, but I digress. To me it seems like an extremely rare case. It seems that it would, in that situation, be easy to tell whether it were a law abiding citizen or a criminal. Behavioral profiling would come in very handy in this type of case. Look at Tel Aviv airport in Israel. That's how they identify threats.
Sounds like they need a little bit of training. If anything, as an LEO I'd take open carry as a very obvious signal that the person carrying is a good guy just trying to stay safe. Hell, if I were a cop, I'd rather people open carry, so I know who's packin'. Gangbangers are still gonna carry theirs concealed. They don't want the attention that comes with OC. They want to walk into a store, keep attention away from themselves, and sneak up to the front and pull their weapon and demand money.
Well, to their credit, at least they're putting it out there that law abiding citizens ought to be armed and learn how to use a gun in order to protect themselves. They know they can't be there all the time.
