The idea
The Terrorism Act 2000, later extended by the 2006 and 2008 acts, have introduced many egregious pieces of legislation onto the books. The unnecessary and illiberal parts should be repealed. Two suggestions from me are:
28 days detention without trial. This is a ludicrously long period, the longest by far in the Western world, and I suggest that it should be shortend to 7 days, MAX. If the police can't charge you after a week, they must release you. Even that's pushing it.
Random stop and search. The police have the power to stop and search anybody with NO justification whatsoever, on the vague notion of being a 'suspected terrorist'. This is outrageous and has no place in a civilized, liberal society. It should be scrapped and the police should need a reasonable suspicion of criminal intent before stopping and searching.
Why is it important?
Simply put, this legislation has no place in a liberal, free society. Some people doubtless think that a free society is overrated, but I doubt that includes the Liberal Democrats and the more enlightened members of the Conservatives. We should repeal terrible New Labour authoritarian legislation like this that was passed for sheer political propoganda purposes.
