None of those riots had to do with the Iraq war or any wars. Most had a big racial component to them. Maybe not that latest big riot --- it was over a change in the school schedule --- which caused the riot and a complete lockdown. They later had a meeting with the parents to explain the schedule change and they started to riot. Most of the gang warfare is between different hispanic groups --- as ironic as that might seem to some.
Yeah, it is ironic. Now, you mention the riot over the Iraq war was in California. I bet these Hispanic gangs are usually from different nations like Mexico and El Salvador.
