How in the bloody blue hell did Poe get convicted of murder? His pregnant wife was threatened by a bunch of thugs in a bar parking lot. That should have been an open-and-shut case of self defense, military training or not.
Which of course still leaves the question of why he was in a federal prison for what was basically a bar fight that got ugly, the feds would have no jurisdiction here, it's strictly as local matter and should have been in state court.
Biased anti-military judge, perhaps. His speech about how Poe is a "living weapon" and must be held to different standards than "normal" men certainly implies he has no love for soldiers.
Along with this, why did he go before a civilian court instead of a military one? Even if he had just gotten honorably discharged, he probably still would have been able to get an attorney through the Army.
