A question of immigration...

You know, it's just occurred to me that if I travelled to France right now I wouldn't get in because my passport is out of date, they'd stop me at passport control and strong-arm me back to Blighty.

So my question is this, why the fuck is it so easy for thousands of immigrants to wander into France and cause such chaos in Calais? I mean, if I went to France I would go there with no intention whatsoever of causing trouble yet they would not let me in because of a small piece of documentation that has a past date on it.

Just goes to show how fucked-up this world really is.
