From the comments of the Mayor and Police Chief, they knew that there was going to be trouble before the game even started. It also appears that many in the “fan zone” saw the riot brewing as the game went on. Why were 100,000 people allowed to congregate in a small area to witness an event that we new was going to bring out emotions – (as well as drunks)? Why was there such a limited police presence at the start of the trouble?  

Young people, who can’t get jobs, see people on the ice taking down million dollar salaries for beating each other, and they want some of the action.  Current issue of Macleans tells us 2/3 of graduating teachers can’t get jobs.  We hear that the riots in Egypt were due in part to young people graduating with no hope of getting a job.

Down in Mexico, this comment was in WND.com:

Rising youth unemployment, easy access to drugs and the quick cash cartels offer recruits are all blamed for felling the delinquency that has cast a shadow over Mexico’s future.
“Organized crime has become a job provider for a section of the population who don’t have a lot of other options,” said Victor Clark-Alfaro, director of the Binational Center for Human Rights in Tijuana on the Mexican border with California.
“Since 2000, the age at which people start getting mixed up in organized crime has fallen,” he added. “And in the last few years, the age has dropped to about 17 or 18.”

We had better make sure our young people can get jobs, or we will see far more of this.  And we had better stop allowing in immigrants who take jobs from our young people.
