One of the protest organisers seems confused by the police presence...
"We are totally non-violent. There is no reason to have civilian police there at all. We are trying to stop the greatest breach of the peace there is, mass murder."
The police are there to stop you getting shot by base security for doing stupid things. The police are there to allow people to enter and exit the base, and go about their legitimate business.
Why don't we take the police off the Faslane gates, and just shoot anyone who enters the base? A vastly cheaper alternative to police constables who seem to be engaged in "catch and release" at the moment. For people obstructing the Queen's highway, perhaps running them over might make them question their resolve.
Actually, maybe we'd better leave some police officers there, to hose the protester's blood off the road.
