Sinkspur flatly stated that the shooter was white. Now he claims he doesn't comment on things he knows nothing about.
If you can't see the difference between hypocrisy and a change of opinion based on new evidence, there probably isn't much I can do to help.
Nope, not much, but tell me, have you maintained one singular hypothesis as to the ID of the snipers, throughout this entire investigative process, which did not require adjustments to your model, because you are, indeed, omniscient?
