The constitution has become toilette paper. Patriot act and all the other 'terrorism' 'security' laws over ride anything constitutional.
Indeed the US has introduce draconian laws that make a US citizen a legitimate target of assassination and torture legalized. Making someone 'dissapear' in internationally held cia prison camps. Locking someone up and forgetting about them. Yes since 911 masses of people have been arrested with no evidence and held for up to 10 years and some even more without any charge or evidence. They were held and forgotten or held until proven innoscent.
There are numerous examples of US captured soldiers, journalists, etc.. and they were not tortured but kept captive until released. All of their interviews I've watched demonstrated that they were taken care of, although initially they were fearful for their lives (naturally) but taken care of none the less and talked to like a human being, even while the opposing soldiers were having dinner they would let the prisoner eat and sit with them and not be treated like an animal like western torture prisons do.
One just has to listen to the stories of all the ex-US detainees and how they were tortured physically, mentally, psychologically, in every which way with some of the most demented and sick means that one cannot even start to begin imagining. In other words, it takes someone trully mentally sick to even come up with these torture 'techniques' and means.
