I've seen so many Apache videos, and it's damn near impossible, on the surface, to tell exactly what they are targeting (although weapons are clearly visible in most, and I do know the sea of red tape a pilot has to wade through to get permission to fire)... Manning is surely a traitor and deserves to die a traitor's death. Do not pass go, do not collect $200. Try him, if guilty (I don't see how they couldn't) and then pull out the old George S. Patton ivory handle 1911 and send that PVT to the final judge.
As far as the NSA whistle blower- He saw the program as being potentially unconstitutional, not treasonous at all. ATF and IRS whistle blowers? They deserve a medal.
