But, as I have been explaining, the slide recoiled and returned before the casing reached that point in its trajectory. There was never any reason for the casing to be blurred, as the "exposure time" on the camera was fast enough. The idea that it was photoshopped is pure, groundless speculation. Particularly since the whole thing was captured as a video that had continuity through the motions.

Look, to give you some idea of how fast the recoil cycle of a semi-automatic pistol really is, I can refer you to the Glock 18 pistol, which is designed to be fully-automatic. No delay between firing cycles. The firing rate is about 1200 rounds per minute, or 20 rounds per second. This means the complete cycle from firing, recoiling, and rechambering is 0.05 second. That would be the same for a semi-auto pistol, only the shooter cannot possibly pull the trigger that fast. That's 50 milliseconds. The average blink of an eye is from 100 to 400 milliseconds. If you blink, you've missed it.

How fast is the casing being ejected? They seldom are ejected any higher than 3 feet. That would mean an ejection velocity of about 10 feet/second. The bullet is traveling 100 times faster. Or compare the difference in speed between an automobile traveling at 100 mph and a pedestrian walking at 1 mph (a brisk walk is 4 mph). Being able to photograph the casing is no big deal. Being able to photograph the recoil motions mean you have to choose the taking of your photo to within 50 milliseconds.

This is all facts and physics. I don't propose to argue about it.
