At some point around ten years ago....in my time as a contractor for the Air Force....they (the AF leadership) suddenly got hyped up and realized that they had various gang groups now in existence. Every PR picture taken for the base newspaper was reviewed for gang-signs (as silly as it sounds). We had one junior airman in the office who was into sports and had a picture taken in some base sports event where she was in some pose....which they used for the newspaper. Three hours after the paper was handed out on a Friday....they had this gal in the commanders office...being asked about this gang-sign she gave. She just looked at them....having no idea what the heck they were talking about, and they had this listing of the common signs (probably twenty of them) and she’d accidentally given one of the ‘forbidden’ signs. They accepted her explanation. Afterwards, I was talking with her about it and we both kinda laughed. This is how crazy it is to be in the military and have all this stuff that you don’t know much about....but be affected by it.
