No it isn't. From that window on the 6th floor, you are looking damn near dead-on at the rear of where the Limo was traveling. From Oswald's vantage point, Connelley was exactly in front of Kennedy because Connelly was in a jump-seat, that was inboard from the door. The jump-seat also sat lower than the seat Kennedy was in which was elevated.
Yet JFKs coat & shirt show a bullet hole 5" down the back, exiting at the tie, too high to hit Connelly unless JFK was noticeably leaning forward. He was sitting upright, as the film shows. Spectors Magic Bullet was necessary.
I have stood there and looked. It was an easy shot.
So have I. It was not an easy shot to this old hunter. Nor was it to any of the Reports experts.
There were at least 5 other people, all strangers looking at the same time, and they ALL said the same. The photos make it look long range and off at an angle. It wasn't long range and it nearly dead-on the rear of the limo.
The tree was admittedly in the way on the first shot; a balky action, buck fever, and a bad scope coupled with no indication of a hit would have made the next two shots very chancy. If oswald did it alone, he missed his calling as a world class sniper.
88 yards?
