Shots fired at Trump rally, page-878

Seemingly

But it is not possible that Oswald was the one.
Kennedy was hit from the front, it blew his brains out the back of his skull and his head clearly lurched backwards when hit.
There were also eyewitnesses to a gunman on the grassy gnole

It seems likely that Oswald was involved somehow and when he was caught he had to be silenced asap.
