No, of course not! Torture gives you false information....better to use proven interrogation techniques....
plus torture/ENHANCED interrogation is ILLEGAL.
No, it is not illegal.
The purpose behind the Geneva convention, was that if you were in uniform, then you were given special protections. The entire purpose of granting those protections, was to prevent soldiers from hiding among the public in plain close, causing armed forced to have to slaughter civilians to get the combatants.
When you intentionally ditch your military clothes, and dress like civilians, you are not covered under the Geneva convention.
IT is not illegal.
Second, every time I look this up, there are plenty of sources that indicate that those interrogations provided clear actionable intelligence, that prevented terrorist attacks, and led to the apprehension of terrorists.
I am not seeing this claim that that it gave bad information. The only people saying that, are people who don't want to believe its true.
From what I have read in numerous places, waterboarding led to the location of Osama Bin Laden's hide out in Abbottabad, Pakistan.
Sorry, but until you provide more conclusive proof, that claim is false.
