Try that outside the Pentagon with a camera! Been detained on occasion but never booked. Got into a frackus at a gun show once years ago where I was on the door (armed) and two plainclothes ATF agents entered, obvious by their body English alone, in search of show venders doing illegal sales. Apparently it is illegal to address them loudly: "Good Morning Officers welcome to the show" over the PA system...after the initial onset it became obvious that the armed venders and myself and our in-house sheriff's deputies outnumbered them and they left to stalk elsewhere. I later ended up guarding the Federal Building they emanated from and we all had a laugh! My job there was to make sure no one parked a rental truck on the street outside as in Oklahoma...or took pictures...
