So you're a 16 years old teenager who goes to highschool, you're not yet allowed to vote and when you try to express your opinion against a future law that everyone consider as stupid by sitting in front of the city hall, some very "intelligent" and "gentle" policemen ask you to leave nicely. The government is close to get the whole France against him now. I don't like to talk about politics because I don't really care about it but that goes a bit too far imho.
To be honest I don't really see the point of the high school students in that fight but maybe I don't know everything about that law. What is for sure is that you don't hurt 15 to 17 years old kids because they stand in front of the city hall even though some "fake students" who are here to fight try to provocate you
The point of the law is, from what I heard to have a non-national examination for baccalaureat and also a more continuous testing system.

Every time I see a CRS (those policemen), it reminds me of the time flags were forbidden in the stadium because of the hard sticks we use to move it. Once I went to a game and my friend had a flag but without the stick, just the tissue part and the CRS told him it was forbidden, even after my friend showed him someone selling the same flag 15 meters after the police control place. Thank God his boss came and we got in the stadium but that was a very funny story showing how CRS are chosen for their intelligence.
