If we take this as fact then...
He was brainwashed into committing murder, but only not guilty because they loaded his gun with blanks, so he should be let out of jail?
Seriously?
Every Muslim terrorist ever born is brainwashed, does that mean they aren’t guilty?
He pulled the trigger with every intention of killing him.
No reason for him to still be alive, let alone released from prison
