The example just represented the feeling. Conversations I had with French fans confirmed the feeling of expectation. There have been accusations of Fifa corruption around the tournament itself, which I can't disregard when it's Fifa.
Regarding Euro 16, I think you may have been deliberately selective. French 'ultra fans' played a big part in the shambles that went on. The French police are also not blameless.
I seem to remember Russian, English, French, Spanish, Croatian, Northern Irish, Ukrainian, German and other nations fans being involved in disturbing situations in France. I wasn't there and am not sure why, but the whole tournament was tarnished with trouble.
What I have witnessed first hand is that French police don't mess about. Their opening hand is often a firm one, which English fans at least won't be used to. I'm fine with that, but there's no need to pretend it was one or 2 sets of fans causing trouble in 2016.
