One more lie. I believe that they, for reasons known only to them, deliberately murdered the poor guy. And now they are trying [quite successfully too] murder his character. The only thing more repugnant than what they did are the bootlickers who defend them.
I'd be surprised if that were true. I think they got hung up in the doorway, the shield carrier slipped and they unloaded. They were wrong about the victim firing, and so I am pretty sure they were wrong about him pointing a weapon at them. Because the safety was on, we can conclude that the Marine had to intent to fire. The "pointing the weapon at them" is a function of their already proven false imagination.
It's been cover-up mode every minute since then.
