Well, I wouldn't exactly say 'Well done French Riot Police' as they didn't really do much.
These 'camps' have been around for a long time. Everyone knows about them, but nothing gets done.
Most of the people do not have any documents, many have false documents. Surely they must be in France illegally? Why are they allowed to stay, they do not want to be in France, they want to be in UK. When UKBA arrest them for attempting to enter UK illegally and hand them over to French police what happens next??
They try to catch the next truck. It's almost like a game, but with only one result.
They just keep on doing what they do until finally achieving their goal.
