A professional would have used a suppressed rifle and shot JFK when he was a totally exposed stationary target, like standing up on a podium making a speech.
So a professional shooter choosing to shoot at a moving target from high up window of a building ( making it more difficult due to accelerating vehicle and ever changing vertical plane angle ) would seem to be a sloppy method chosen by the shooter.
That MC rifle found on the 6th floor TSBD at 1:20pm is the biggest problem for a CT because if the rifle was not actually fired, then it was either pre planted by conspirator shooter or it was post planted by conspirator member of Fritz team or by FBI.
If the conspirator shooter intent was to set up Oswald, then using the MC rifle which had paper trail to Oswald, would be the more convincing option than the shooter just pre planting the MC rifle and the shooter using some other rifle , risking leaving different type shells behind and different type bullets that might be recovered from JFK and JC.
The desire of the conspirator shooter to set up Oswald, therefore, is the reason why an otherwise professional shooter would choose a sloppier method of A: using a poor quality MC rifle with misaligned scope( or at least preplanting it) and B: choosing to shoot from the TSBD 6th floor 72 ft up and having to adjust lead for changing vertical angle and an accelerating limo moving away at ground level, as well as having to contend with traffic light and tree branches in the way.
A professional would have used a suppressed rifle and shot JFK when he was a totally exposed stationary target, like standing up on a podium making a speech. Agreed.
There's no way a professional would have chosen to take a shot from the TSBD building at a moving target.
Again, imagine the planning stage - he's assuming he would have access to the building, that no-one would recognise a complete stranger in the building, that the 6th floor would be empty, that he could simply walk out of the building etc.
And wasn't it lucky for him someone had constructed the Sniper's Nest before he arrived!!
If any intelligence/military element were involved they would surely have had countless opportunities to get close to JFK.
The shots from the TSBD building seem like a desperate option.
Like John said, the shot shots were taken from here because there was no other option. It was the only available opportunity.
The shooter was clearly familiar with rifles but not a professional marksman.
The need for three shots indicates this but the fact one shot missed everything all but proves it.
Thinking about the first shot - the target would surely be the centre of JFK's head. The first shot is low by some 8 to 10 inches. Even though it hits JFK it's still a miss. The shooter then makes an adjustment and the second shot hits the target. This might be because the scope on the MC was off.
The first shot is the easier shot. The 'cross-hairs' are lined up on the centre of the head but the shot is low by 8 to 10 inches. The shooter sees this and makes the adjustment while tracking JFK's head for around 5 seconds.
