Show me something that supports your position. Grogan died with a functioning weapon that still had six rounds of ammo, yet he failed to engage Platt before Platt fatally shot him. That he was aware of Platt's presence and his intent is suggested by Hanlon's testimony about Grogan's exclaimation immediately before he was shot.
Hanlon's testimony about his own encounter with Platt states that he watched as Platt aimed the gun at his head, and then changed his mind and shot him in the groin. No mention of any offensive or defensive acts, just passively taking a round to the groin.
Dove is less clear of a case, but the fact that he took two closely place shots to the head from from a man who had a disabled right hand and who was having to improvise trigger manipulation suggests that Dove was not an active target at the time he was engaged.
I'd certainly like to see any evidence that suggests otherwise.
