In this case where Trump pardoned the guy, the Army deliberately withheld exculpatory evidence.
Did you look at that statement with anything like a hint of skepticism? For if that were true and an established fact, the man wouldn't need a pardon, because the conviction would likely have been thrown out on appeal. But his appeals were dismissed.
So, where did you find that crap? And, you didn't willfully confuse Behenna's mere claim that "exculpatory evidence" was withheld with an actual fact, or did you?
Behenna is a murderer. He humiliated an Iraqi, interrogated him after the man had been exonerated, and, in the best reading, went about it so incompetently that the man had a chance to go after Behenna's weapon, and he couldn't control the situation without murdering the man. More likely, he was outraged and out of his mind that any of Those people had the unprecedented temerity to fight back against an occupying force.
Trump's pardon will be widely perceived, throughout the Arabic / Muslim world, as more evidence that mollycoddling murderers in the oh-so law-abiding and human rights-upholding West is the thing to do, not least because the lives of Those people count for nothing. How do you think that will play? Behenna's murderous rage, along with Trump's propensity to "stick it to Them", are likely to cost quite a few lives.
