Those riots have a mixture of causes of course. Interestingly muslims who have work and who have the access to education and chances tend to be much more moderate than young muslim males with absolutely no perspective of a normal, pleasable and satisfying life. To be a young muslim out of a banlieue means that you are trapped in the lowest social class you can think of. Since those guys have nothing else to be proud of they escape into their weird religion.
Because France has to live with its muslim immigrants in the future (the only way to get "rid" of them would be mass murder - thank God since the end of Hitler we overcomed such BS in Europe) it has to integrate them. This will only be possible if they are given the chance to be real Frenchmen (or real Brits, Germans etc.). To get that they need work, education and culture. It is the duty of the French administration to provide those chances to its citizens instead of welfare cheques.
Those beurs have to undergo a mixture of demand and assistance from the state to condition them for a normal life. On one hand they have to understand that they have to behave like everybody else on the other they need the chance to be like everybody else.
