[Monterrosa-24]

If you think a blood spray in the Zapuder film indicates death then you are not familiar with bullets wounds and trauma. One can have huge chunks of skull blown off and survive.

In JFK’s case the bullet’s path was fatal but he was indeed alive (pulse, blood pressure, neuro activity) when he reached Parkland.

[The Louiswu]

"he was indeed alive"

He was alive in the "he was still breathing sense" but once that bullet entered his brain, he ceased to be John F. Kennedy. It just took a little while for the body to catch up with what the bullet had done.
