Who's rioting in Paris? How do journalists say it?

Add Paris to the list of riot-stricken cities in the Submline song "April 26, 1992."

But what are these riots about?

Good luck finding out who the rioters might be - or what their motives might be - in this CNN.com article.

It's not until the 15th paragraph that we get this:

The area is home mainly to families of immigrant origin, often from Muslim North Africa, AP said. It is marked by soaring unemployment, delinquency and other urban ills.

OK.

Now of course journalism ethics indicate reporters shouldn't speculate on people's motivations too much, and people's race or religion should only be mentioned when relevant, but isn't it here?

The counter-point, of course, is that other articles that mention such info in the second paragraph might be accused of pointing the finger at a group unnecessarily or theorizing about causes without having taken a survey:

Youths who rampaged overnight left a trail of burned cars, buses and shops in nine suburbs north and east of Paris, home to North African and black African minorities frustrated at their failure to get jobs or recognition in French society.

Do you have a quote from a rioter who failed to get a job? Did he say, "I'm going to torch this car because I'm not recognized in French society."?

All I know is it's easy to criticize journalism, but people in the profession are working diligently to paint as accurate of a picture as possible, when people on all sides are busy accusing them of bias.

(Well, I should say "many people in the profession." I haven't taken a poll or conducted field research, and I'm sure there are plenty of them who show up late to work or write in their blogs when they should be working.)
