Pretty much depends on where you're doing the shooting. At the range nobody seems to bat an eyelid.
Out in the desert, the GFD, sheriff, border patrol, etc are paranoid, especially with all the drug runners/human smugglers shooting anyone with a uniform these days. I can't really blame them for being heavy handed. My next door neighbor and some friends went shooting out in the desert and they got buzzed by the sheriff's chopper.....
