Just been watching this on the news. I just don’t get what they want to achieve by sitting down and putting a giant boat in London and having 680+ of them arrested!!!!Why is there not a law that makes obstructing the highway a criminal offence. Then the police can arrest swampy and the great unwashed that are blocking up the roads and bridges in London and causing chaos. The police should have stopped them right at the beginning, they could be there for weeks now.
