For those who have missed the point, it's not about terrorists, killers and immigrants. It's about the right to arrest anybody and hold them on suspicion of terrorism without actually having enough evidence to charge them, for up to 6 weeks.
Why do they need this law? Surely they would have a fair enough reason to arrest someone in the first place and if after 4 weeks of questioning and investigation into that reason, they haven't found any evidence of wrongdoing, then that means that either a) the police aren't very good at their job, or b) the person arrested hadn't actually done anything wrong in the first place.
I can't think why the government are using up so much of their precious time on this issue when there are so many other problems in this country that need addressing.
The way some people go on you'd think that every train, plane, and auto(bus)mobile had it's very own terrorist on board, waiting for the call to blow everyone to kingdom come, were it not for the government and it's policies protecting us all from certain injury and death.
Who was the last person in this country that was released without charge after xx many days behind bars, who then went on to commit an act of terrorism?
