Not a doctor, but it would depend on WHERE in the throat the bullet passed through. It obviously missed his carotids and jugulars or he would have bled out. And it missed his spine or he would have died immediately. So theoretically he could have climbed out like that if the bullet only hit muscle and soft tissue on the passthrough. But then you have the news reports saying he was semi-conscious from blood loss. That’s the problem; all the reports contradict each other. I think they’re just making this up as they go, trying to fix one lie with another one.
i’ve also wondered about the trajectory. If the bullet passed through his neck right-to-left or left-to-right, right through the larynx, then to me it would be a deliberate silencing of the only surviving witness. Note in that photo of him on the ground, it’s ATF and FBI, not the local LE (man on the right may be Boston PD; can’t tell).
well now we are hearing he had no gun...so he couldn’t have tried to shoot himself in the boat.
