Yes, but...
"Detention, without trial or without charge, for up to 28 days. And that was a compromise. Blair wanted 90. Think about that. You can be lifted by the Police without warning and without evidence and held for a month."

I get your point, but think about it. In practice, do the police really just pick on some poor unfortunate law-abiding citizen and throw him in jail for 28 days without evidence or charge?

No, not really. They will only use these powers when they have strong suspicions that the person is involved in terrorism. They might not *yet* have the black and white evidence, but on the other hand they're not going to act without damn good reason.
