Or were they told that the location was off limits on that day, for good reason. And they chose to go there anyway.
^^This^^. AFAIK, the police started by asking them politely not to go to that area at that time. Perfectly decent request. CM took their usually “sticking it to the man, man” antagonistic approach to this.
Asshats, total asshats.
As to the “stamped out by force”, have a look at things like the Countryside Alliance march, the Stop the War coalition march, and more. Massive, peaceful marches, where those taking part weren’t antagonistic asshats with chips on their shoulders. Oh, and quelle surprise, no trouble.
CM are bad for cycling. Their approach, of pretty much trying to find “controversy” at all turns, gives a bad image of cycling at a time when it’s really taking off. We need people to embrace, understand and enjoy cycling, not just think that anyone on a bike is an antagonistic asshat.
