French PM On TV

Dominique de Villepin, the French Prime Minister was on TV tonight. To my surprise, he didn't do such a bad job overall, given the current situation and especially compared to Chirac's shameful performance last night. At last it looked like someone was in charge.

Among other things, he announced the possibility of curfew in its city suburbs 'if necessary' (decided by the prefects). The curfew decision, he said, would be made at a cabinet meeting early Tuesday with the approval of President Jacques Chirac. Villepin said

'Everywhere it is necessary, the prefects (regional authorities) can, under the authority of the interior minister, apply a curfew if they think it useful for a return to calm,'

Local government officials will decide, "which neighborhoods are the most sensitive, where they believe such measures must be taken".
My question is.. how will they enforce it? What police are going to be used? Given the current situation, that's not going to be easy.
More interestingly, after a question by the newsanchor about the rumors of viligantes in some areas, the Prime Minister did not condemn that the "formation of civil groups in sensitive areas if their goal was to convey a message of calm and restraint. "
I must say that at this point, I don't think this is such a bad idea - the situation will only improve if the locals decide to work together with the police and the authorities. They need for instance to kick the younger kids into their homes at night! More than half of the arsonists and rioters are under 18. Needless to say that the question of parent responsibility is one of the many topics discussed here.
So now, we are once again bracing ourselves for another night of possible violence in some parts of this nation. Hopefully it will lessen soon.

[In the meantime, for a break from the riot issues, I'm going to watch Kill Bill2 on tv.... want some violence? now we're talking!]
