IMHO:
I believe it was an assassination, funded by the government or not, I don't know.
But, one made from the gutter. directly next to the street.
After engaging the president, the gunmen only had to walk out of the gutter, man sized by the way, to the spill way next to the rail station.
Being a resident of Texas. I have been to the site on many occasions. I looked at if for an hour while eating lunch after processing for the Air force. And I could in fact picture a shot from the sewer/drain.
Looking at the video, I see the presidents had lunge backward and a few seconds later, forward again. I am not sure if it was a muscular movement forward, or a shot by Oswald. But a shot from the front right was the first.
Only my opinion, nothing more. I will read all of your posts with respect.
