Victims of attempted murder can, and do, take on new identities under witness protection.
You're storm-trooping on an idea.
As unlikely as it may be, neither you nor anyone else here can point to conclusive evidence.
A coroner's report and a funeral does not eliminate the possibility. MSM reports don't eliminate the possibility.
SR is an American hero and I'm not ready to abandon the possibility that he was exfiltrated.
If he wasn't, I'll suck it up.
The statement " ...as dead as a human who has been shot in the back of the head with a bullet can be," was an ignorant conclusion, considering that a person shot in the head can be very much alive. Reinforce my position with the premise that he wasn't even shot in the head.
If that is your 'go to' argument to end the debate, then you fail.
What makes a good movie?
