AFAIK, it's not the entire population of these suburbs whois riotting/demonstrating.
Yes, there are serious economic/social problems in these areas and these people need more help than tear gas.

IMHO, it's only a few stupid (for sure), disoriented (at the least), manipulated (may be, if only by TVs) teenagers, having some fun.... <img src="/images/graemlins/crazy.gif" alt="" />

And exploiting these incidents, reporters and political people try to give them a political meaning...
There are grounds for political unrest, but these events are not related.
Not at first.
But let TV et politics manipulate all this, let them "pour oil over the fire" and then ....... it could really turn into revolt, they just need a little time to succeedl. <img src="/images/graemlins/mad.gif" alt="" /> <img src="/images/graemlins/mad.gif" alt="" />
