Let me be just a bit provocative here: If you have violent gangs, usually heavily involved in crime and drugs, social media is the least of the issues. The US has a serious, nearly unsolvable problem with inner city culture. Broken families, zero interest in schooling (by parents or kids), shoplifting and looting, drugs, violence. You don't need to regulate social media. You need to round up the delinquents, get them out of normal schools (where they do nothing but disrupt), and put them into military-style institutions, where their behavior can be controlled. Stop handling criminal teenagers with kid-gloves. If you don't break the cycle, this generation will just go on to create the next generation of teenage gangsters.
