Well the last part definitely doesn't match what's in the video. Without watching the video again it seems to me that the cop could have been trying to stop the bicyclist to issue a citation and resorted to tackling when the cyclist (bike rider) didn't comply. It's hard to say, not that it makes the tackle right necessarily...
Let's face it, theres a good chance that the rider was impeding traffic and breaking traffic laws, that seems to be what these CM rides are all about. The cops could have been standing there so that they could catch one in the act. I don't see why the CM folks think that they're helping the cause by blatantly breaking traffic laws and irritating drivers, seems to me that they're having the opposite effect...
