of course it does, but it would have a different effect on the accuracy of your shot according to the angle of the shot.
if you shoot directly down, gravity has no effect on the accuracy of your shot.
if you shoot directly horizontal, gravity will change its trajectory by X.
if you shoot at an angle from the book depository, then gravity will have an effect on the trajectory between 0 and X.
so the rifle would need to be calibrated differently according to the angle.
Here's a link that explains the impact of gravity on a projectile.

Snipers take a lot of different variables (including gravity) into consideration when firing, the farther the shot the more variables they consider and the more the "flight" of the bullet is affected by these variables, but we're talking about shots of more than 300 yards, some of more than a mile, but in the instance of the JFK assassination, the biggest variables would have been wind direction, windage, elevation, and the speed of the target.

"But then with me that horrid doubt always arises whether the convictions of man's mind which has been developed from the mind of the lower animals, are of any value or at all trustworthy. Would any one trust in the convictions of a monkey's mind, if there are any convictions in such a mind?" - Charles Darwin, in a letter to William Graham on July 3, 1881
