The truth of this is that the officers who shot were in plan clothes as was the officer who was shot. We have only the word of the living officers that they called out a warning, what we do know for certain is that six shots were fired and there was no return of fire. This just appears to everyone in the know that they saw a black man running with a gun, shot him and faked up the protocol later, a la De Menezis et al.
