So the Old Movies Had it Right
You know how cheesily the old movies would portray soldiers getting shot - suddenly stopping their movements, then dramatically crumbling in a I've-been-shot fashion and rolling over flat on the ground? As opposed to newer movies where the shooting victim gets basically blown away, hurled backward by the force of the bullet, landing splat on the ground. Well, from the surveillance video of the Empire State Building shooter getting shot by the police, it looks like the old movies had it right.
Here's the video - aside from the color and the clothes styles, it looks it could have been staged by D.W. Griffith:

Evidently conservation of momemtum is coming back into fashion.
I guess. From a bit of Googling I learn that the typical 9mm Cop gun fires an 8 gram bullet at 375 m/s. so if fired at an 80kg man, given M(1)V(1) = M(2)V(2), and assuming complete transference of the bullet's momentum to the victim, we'd have .008*375 = 80*V(2), so the bullet should force the shooting victim to move at a speed of 3.75cm (1.5 inches) per second, which is like barely moving at all. But unfortunately for the shooting victim, much of the bullet's force is dissipated in doing stuff like tearing through skin, shattering bones, ripping through soft tissue and internal organs, etc.
I never thought about it before, but I see your point - hard to imagine how a bullet could send a full-sized person flying backwards and smashing into a wall.
You mean this isn't accurate?
Pretty sure that couldn't happen. The bullets fired from Mr Willis's guns appear to be sending the bad guy reeling backwards at a velocity of around 10 ft per second. For that to be the case, those bullets would have to weigh over half-a-pound each - assuming they're striking him simultaneously.
But I guess the advantage of this kind of shooting is you don't need any dramatic atonal crescendos from the soundtrack or an overdub of the dreaded "Wilhelm" sound effect.
How about the cops just running up to him and acting surprised he had a gun. Wow let's stop running and shot to save our lives. As a training film this will be how not to approach a gun toting killer.
Yeah they're lucky he was only interested in killing the one guy he loathed otherwise they were sitting ducks.
