The issue of torture back for centuries, regularly, to the headlines.

The treaties on 'ineffectiveness of violence are not in fact new.
To stay in our latitudes, already in 1770 Pietro Verri, one of the fathers of Italian Enlightenment, he had rebuilt the facts trials of alleged spreaders of the plague in 1630, concluding that many of the admissions made by the victims of torture had misled justice, It is precisely extracted with inhuman methods.
L 'Italy is not immune to the question of violent methods and that of the Diaz school is only a glimpse, in a boot where the law on torture is lost between the opposition and never reaches the finish line.
In 2015, according to Amnesty International, there are 150 countries that have ratified the Convention against Torture, but despite this, torture and martyrs are still in vogue even in some of the states that have formally abolished them.
The torture and its effects are therefore still present and still enter the media radar even after the declarations of Donald Trump, who, a few hours ago, reiterated that torture is an effective method to combat terrorism.
The President then went back on his feet, arguing that the US is not in favor of torture, and that he had merely said that, according to him, it is a method that gives results.
Meanwhile, the Washington Post published a draft of a decree authorizing the CIA to restore the black site, or secret prisons abroad.
Again nothing really new: George W. Bush had blessed them with Enhanced Interrogation Techniques program, the enhanced interrogation techniques used to get information from terrorists and assumed, criticized by the US Congress and banned by the Obama for being too similar to torture, damaging the image of America in the world and because it is only partially effective.
However Dianne Feinstein, the Democratic senator and chairman of the Subcommittee on Terrorism, author of the report that disqualifies the program implemented by Bush, has not taken the state secret on the entire documentation consulted.
It should also be considered to have a more detailed picture, which Feinstein is still a fervent supporter of the death penalty but the final consideration of the long report says that "the program's methods are not effective for getting accurate information nor the prisoners' cooperation."
The collective Journalist's Resource, a research center that analyzes the news in the light of scientific evidence, concluded that violent methods to obtain information do not work.
The treaties under analysis are all in English and, in most cases, are scientific or academic texts.
Christopher Hitchens, one of the journalists who participated in the research, has tried waterboarding on her skin, telling they had experienced feelings of panic, wondering what he would do if, suffering the same experience in reality, he was the wrong man to whom ask questions under torture.
(The video, in English, contains particularly brutal sequences and, in any case, are similar to those we normally see in movies and TV series)
The content of refereed publications concerns in the same direction, summed up thus: those who torture does not know what truth is looking for and so is not able to fully recognize it even when he gets it.
Those who torture the sufferer is usually also tortured after saying what he knows, so to speak becomes useless.
The collected statistical data are not sufficient to validate the usefulness of violent methods during interrogations or indicate that the information obtained will prove useful in fighting insurgencies or terrorism.
To these considerations, which can be consulted online, add the statements and explanations given by former CIA agent Robert Baer and Porter Johnston Goss, who headed the CIA from 2004 to 2006.
A particularly cruel torture method, according to Baer, is able to get any kind of confession from anyone.
That confession is useful or real, is a whole other kettle of fish.
Goss, in contrast, recognizes certain types of torture, waterboarding of all, a professional appearance even because, says the former director of the CIA, the brain reacts as during a drowning.
The cerebral hypoxia - or the absence of oxygen - due among other things also a poor judgment that also impacts on any statements made by him who is undergoing waterboarding.
At the end of 2014, Edward Snowden has centered the finest part of the question, arguing that even if it were effective, torture is still justifiable.
In the absence of such a contribution to the issue, any debate on the issue of torture becomes even grotesque.
The Pew Research Center released yesterday the results of a survey conducted in late 2016, its opinion that Americans torture.
The result is a glimpse into two people with 49% opposed and 48% approving torture in limited cases.
The percentage of opposites rooms among black people, Hispanics and women.
One interesting fact: among those who believe that torture unacceptable regardless, 67% are of the democratic area while only 27% is close to the Republican or Republican ideas.
