The Yellow Jersey crowd does not seem to be intimidated by France Police. I think an insane Muslim will not deter them.
If a false flag the government might be trying to persuade other French citizens to consider them in the same class as gun wielding Muhammadan scum instead of patriotic heroes manning the barricades against government oppression. Still, I do not think a Muslim requires too much reason to jihad and I suspect the French people will know the difference.
