As Kohny Depp's character said (something like it) in "Blow":

"I went to prison with a Bachelors in Marijuana but I came out with a Masters in Coke"

Of course if you lock them all up you can use them as bargaining chips and 'free' them say, at a ratio of 800:1 like the Israelis do whenver one of theirs is captured by the peaceful peaceloving people of peace.On the other hand, with simple imprisonment abused women all over Britain would then be free to get jobs, walk around outside, not get murdered for dating outside her own family, etc.

Deportation not fair, says Islamic extremist (he's on welfare & benefits)
 

I say deport him. The irony is that he'll whine that his life will be in danger in his own country if he's forced to go back there. I don't see the logic of deportation. Surely it would be better for them to be in prison where they can't be any more danger than free in another country. Isn't it just moving the problem on to somewhere else so we don't have to pay to keep them in prison?

Deportation is supposed to have a psychological effect. Put the fear a God in 'em. I would imagine that among extremists, jail is actually an award.

I guess it would be 'unfair' to imprison him too because so many people depend on him.

Don't throw yourself on their mercy, it's a godawfully small target.
