Oh dear God, Shane, get over it and get a life.
We "know" insofar as anyone not physically present or with indisputable video footage can "know", that the overwhelming physical, ballistic, and eye witness testimony supports the facts that you see assiduously dance around. Period.
We get it. You took the wrong side in this mess. You threw your weight and considerable daily post count behind a cause and narrative that proved empty, and now you likely feel like a dunce. You looked the fool, and got called on it, and life goes on.
Continually beating the "I'm not saying he murdered him, BUT...!" drum in a quaint effort to distance yourself from your original bellicose devil's advocacy pronouncements fool exactly no one.
