I hope I'm wrong on this point, but he probably won't be convicted. Just like all other police shooting incidents, the department will bully witnesses, destroy evidence, and lie on the witness stand to protect one of their own.

Cite one specific example where any of the above actually occurred. In reality, not your fevered imagination.
