It also shows their lack of intelligence and strategy.
This what happens when people gather on facebook and decide to set up unsanctioned demonstrations, without any proper organization or security precautions, then participants start doing stupid things, then hooligans, extreme-left/right come over and spoil everything. The end result is anarchy.
At least two people died a few days ago, not to mention the hundreds of injured and devastation. This is the consequence of amateurism and improvisation.
Besides, the government has nobody to talk to. There are thousands of people shouting and demonstrating across France but nobody to represent them. No structure, no manifesto, no consistent program.
If you want to challenge the authorities, you need to be smart and organized. At least as much as they are.
