I might be mistaken, but I think Jeff22 was referring to the choice of clothing, i.e. the T-shirt that said "Keep Calm and Carry Guns". I don't think it's appropriate to wear attire like that out in public.
I have plenty of T-shirts with cool graphics and sayings from a lifetime spent in the Army and in Law Enforcement. I wear them on the range, at training session, but not out where someone might think I am an armed wise guy or still a working cop.
There have been plenty of threads here and in GGD discussing not wearing the CCW "uniform", i.e. fanny packs, photographer's vests, 5.11 pants. Personally I think one blends in better wearing those things then wearing gunny or cop T-shirts.
Personally I always try to dress the way the others doing the activity I am engaged in are dressed. That way you don't stand out and draw the wrong kind of attention. Just good tactics.
I had a rather comical experience some years ago at one of Pat Rogers Carbine Courses in Lebanon, IN at the Boone County Sheriffs Office.
It was the end of the first day on the range and I was back in my motel room. I always took enough loaded magazines to get me through a day of class so that during breaks, while everyone else was stuffing magazines, I was actually taking a break.
Anyway it's about 1730 I'm sitting on the floor between the beds in my room loading magazines. On the bed were my two M4s and My Kimber Warrior. I'm wearing khaki 5.11a and a black GemTech T shirt with a picture of a suppressed M249 SAW on it. The door to the room opens and I jump up reaching for my pistol. A couple who had just checked in were mistakenly given my room because when I checked in the day before the clerk put one night instead of 3 in the computer.
I can only imagine what they must have though when they came into the room. There was this guy 6'2", 250 pounds, wearing a T shirt with a machine gun on it and khaki cargo pants, with weapons, standard capacity magazines and ammunition all over the room.
I would love to have a photo of the look on their faces when they walked in. Humorous now, but I'm sure the combination scared them to death initially.
