So saying publicly and proving that USA kills and tortures people undermines your freedom?
So what? Did anything happen thanks to that?
He stole and released critical intelligence that could result in harming diplomatic relations, and put American soldiers lives at risk during wartime (which is aiding and abetting the enemy). He intentionally violated the Espionage Act, and as someone with a security clearance, he knew the risks. Violation of the Espionage Act carries with it a penalty of death.
If he was unprepared to accept those consequences, he should've kept his treasonous mouth shut.
Hint: the red question just needs a Yes or a No
Hint: the green question just needs a Yes or a No
The first is not a "yes or no" question, because it is a leading question. It doesn't really matter what the classified documents reveal, because stealing and releasing classified documents is illegal and a clear act of espionage. If he felt that something illegal was happening, he should've gone through the proper channels and had it investigated.
For your second question, yes.
Oh, okay, so he should have let the torturers and murderers investigate their own crimes. That's a great idea! How about we let regular lawbreakers be the judge in their own trials?
The government is not a hive mind, nor is everyone in the government (or even most of he government) complicit in the alleged crimes....and yes, government officials investigate other government officials all the time, it's how the justice system works.
