Ok following up to your post, I’m going to go down the rabbit hole with this post. I live in an area with gangs, i.e., MS-13, etc. the gangs have many specific ways to show their affiliation—haircuts, shirt colors, and social media pictures. In fact, many schools ban specific colors because it can start turf wars. What if posting the picture is a signal of sorts, that they are open to overtures or association, maybe not necessarily in a gang, but they are part of a group, maybe first serious crime committed? jMO, IMO
