Did this guy lay a hand or weapon on the dead guy?
No, what's that got to do with it? He let this happen in Black History Month! They get a "get out of jail free card" on Black History Month.
No, but apparently he lied about the reason for pulling Nichols over and dragging him out of the car at gunpoint. I suspect the Memphis PD by now knows the real reason he was targeted. If it was a conspiracy to target the victim, Hemphill will probably be prosecuted, depending on what he knew. Getting fired might be the least of his problems...
