Can you clarify something about the PATRIOT Act?

You don't need to docment anything and you don't need to ask the judicial system, anything... If you have "suspicion" a person is a terrorist or as such, then you can search them/their belongings without a warrant, arrest them without a warrant, keep them as long you want without a warrant and never tell them why they this is all happening to them in the first place... All of this can happen without consulting any judicial system.
