WAS it a protest? I can't find much about it at all. Mostly a video. None that even say WHY it started.
EDIT:
Ok, found THIS...
Witnesses told KTLA the fight started over an incident at the hotel pool, when someone pushed a child into the water.
Raymond Brown, an 11-year-old who was at the pool at the time, told KTLA he playfully pushed his little cousin into the pool. His cousin then accidentally fell on a group of girls.
“They wanted to try to fight us but we didn’t really do nothing. It was just an accident,” Brown said. “And then that’s when they tried to fight us and they all went to the basketball court, and then we got in the hotel and they just started throwing bottles and stuff at us.”
