CK? So they’d better not wear anything with the Calvin Klein logo, either.
You may be right. Gang bangers frequently put out signals of their affiliation, looking for counter-signs, friendly or enemy.
This can get bizarre, because they get so focused on this, they look for gang signs everywhere, even far out of their ‘hood, and from people who obviously are not gang bangers.
I got to examine this first hand, while in a good neighborhood far away from any gang area, driving with an elderly man. At the time I was wearing a cowboy hat and mirrored sunglasses. Leaving a grocery store parking lot, I asked him if we should turn right or left for our destination, and held up my hand to point in either direction. He held up his hand to point right.
Just then I noticed two gang banger types in a cruddy car, with colored bandanas on their heads, and a look of utter rage on their faces, vigorously making gang signs to try and attract my attention. Fortunately they were perpendicular to my route of travel, in such a way that it would have been difficult for them to maneuver their cruddy car back towards us, or even to take an effective shot if they had been armed.
Which would have been foolish, because at the time I had a sawed off shotgun holster with a side by side of 00 shot.
