I'd say that human rights should be set in stone, since any relaxation of these laws, no matter how good the intentions, might lead to trouble later on. Even the laws that Blair is hoping to bring in now are a bad idea. It essentially gives the government the right to deport people without proof of involvement in terrorist activites. As I'm my own MILF has said, condoning terrorism isn't a crime, despicable though it may be. Many of the proposals are sensible precautions, but those which interfere with human rights are a step too far.
