Climate protesters sent a British policeman to the hospital with head injuries over the weekend:

Activists in Europe are aggressively practicing civil disobedience, and more, in their actions against the coal industry.
In the latest confrontation, police in the English county of Nottinghamshire arrested more than 50 protesters at a coal-fired power station over the weekend when scuffles broke out with climate campaigners.
According to news reports, hundreds of protesters were trying to break through a security fence around the plant, which is owned by the giant German utility E.ON. One police officer who sustained head injuries was reportedly airlifted to hospital.
A blog posted to a Web site run by the Camp for Climate Action, which was helping to organize the protest at the coal plant, wished the officer a speedy recovery.
The blog also said that the police had injured several protesters and that the injuries included “dog bites, a dislocated ankle and head injuries.” The blog noted that group was at the plant “to confront the causes of climate change, not get into conflict with the police.”
