I'm French and I really don't think this law will ever pass. Not how it's currently written.
In France, we have something called the "conseil constitutionnel" which checks that every law voted by the parliament is in accordance with our constitution. This law violates a lot of basic rights. For example, the "presomption d'innoncence" guaranties that people can't be arrested without proofs, and that they don't have to prove that they're not guilty; the government has to prove that they are.
The law will be reexaminated as soon as the government can afford it, and , given the domination they have amongst the parliament, the law will probably be voted this time.
This is still a nice thing. It's letting some time to the people who are against this law to organize themselves and inform people about the obvious constitutional violations of this law.
It's more likely than not that it'll sneak in somehow. But it's less likely than it would be in America. Americans lack the ability to form strong emotional responses to abstractions; we'll only riot in the street over actual video footage of somebody being beaten or shot by police. In France, they'll riot when a law that allows things they don't like is passed, not just when someone identifiable as Authority publically does something they don't like.
