If you're just rambling around Phoenix, AZ with your slung AR-15 and decide you need a cup of coffee, the Starbucks at Sky Harbor should probably not be your first choice of places to wet your whistle.
You're not helping, Peter Steinmetz.
As my roomie pointed out, there are plenty of pictures of IDF reservists somehow managing to enjoy a frappaccino without unslinging their shootin' iron and muzzling passersby. (And, as I replied, the only reason the IDF reservists in question are carrying those AR-15s is because they have to be armed and aren't issued pistols; a restriction that does not apply to private citizens in Arizona. Steinmetz could have had a sidearm conveniently strapped to his belt leaving both his hands free and not caused a tenth the fuss, but I presume that would not have suited his purposes.)
