“About 10:30 p.m., it turned into a riot with people in the crowd tearing down stop signs, setting mattresses on fire,...”
Okay, who brought the mattresses? Do people normally bring mattresses to a party or riot?
That was my first thought as well... how are there always random mattresses laying around when trouble is brewing? If I ever see some mattresses in unexpected locations in any numbers whatsoever, I think that’ll be my cue to get out of Dodge.
Nihilist college students...
When I attended UCSB way back when, mattresses would appear at parties from time to time to soften the fall of those people who would take in too much nitrous oxide. How these kids ever got their hands on a tank of N2O was never learned, but this was quite popular in IV at one time. It looks like the student ghetto hasn't changed much since then as riots and wild parties were common there 30 years ago. Stabbings, not so much. But there was always a population of non students in this town that were scary people.
People bring mattresses to a party or riot if they are really stupid.
