I didn't know that about gangs. I hope I'm not the only one on FR.
I thought he wore blue so often because he might have gotten the impression he doesn't look good in earthtones. ;) Or that it was his way of signaling to someone involved in the cover-up, like Clinton wearing Monica's tie.
Do a Google on the words, "Crips, Bloods, colors" and you'll get a whole lot of info. I didn't know about it either. (In fact I have a sportshirt just like Joran's blue plaid one that I bought at JC Penney's).
I was researching the colors, since gangs have wormed their way into our fair city ( a small city in the Northeast), and there was a gang shoot-out near the hospital, one kid killed. So, I wanted to know how to recognize gang members if I see them.
It's an eye-opener!
