It's unfortunate but it's what the French police do. I've suffering the effects while sitting in bars in Paris and Nice because someone kicked off at other bars and it drifted in the wind. Sad that a relative few (if you are looking at 40,000+ kopites) who were there had to suffer for the actions of the fakers and bunkers in,but they and the media are using it to try to whitewash their guilt. Remember as unpleasant as it is to be effected by tear gas,nobody died. There are supporters in Italy who won't be showing much sympathy.
