My suggestion is contact the local paper and hope some reporter will touch this story. Use the angle of the memorials being stolen, not the other issues. The memorial missing might be more newsworthy than a small scale conflict. And the reporter may take the conflict to make a bigger story out of it. It may only get a brief written but I think most people are respectful of a memorial whether they agree that cyclist should be there.
