The calm before a riotus storm

I was chatting Thursday with a colleague who noted that this week’s police log was relatively quiet although Chico State University students were back in town. I theorized students might have been more studious because the economic downturn.
Well, Thursday night wasn’t so quiet with a disturbance that some called a riot.
As an observer, I find it interesting how these situations develop and where. It’s worth noting that the two incidents this school year (including one in October) didn’t necessarily revolve around calendar events or even specific days of the week. In years past, Chico riots seemed to most often be associated with holidays or events such as Halloween or Pioneer Days. Not necessarily the case now.
