WBUR follows up on Monday's whatever-it-was, talks to kids who used Facebook to get their friends to show up at the beach just to hang out, and Boston Police, who said there was no indication of a "gang issue" Monday.
State Police told the station that at least some of the fights were a result of gang rivalries, but even they acknowledged that the vast majority of the people there had nothing to do with gangs.
The Globe reports Mayor Menino's gotten involved, asking State Police to "act more like Boston police" in dealing with disturbances.
