Yes, it works where the protest culture is already in place. You can't ask Americans to do the same, someone will inevitably bring a gun and it'll go south very fast, as it happens almost daily in all sort of public demonstrations, peaceful or not, in the US.

There is no points of comparison between the US and France when it comes to protests. LA riots, black panthers, vs may 68 and yellow jackets...

Regarding LA riots, black panthers, vs may 68 and yellow jackets, there's a world (an ocean?) of differences between the reasons which lead to each of the events, with the situation of blacks in America having nothing to do with the situation in France today and the same with the start of the LA riots vs the start of May 68.

So, get rid of the guns.
