You saved the day right? Oh no that is just the start, since the round fired was a 7.62x51mm NATO (there is no “rubber” round for this firearm) it went straight through the torso of that protester with a box knife and into and then back out of at least a few other people in the dense crowd (must be their fault for not wearing better body armour). The gunshot is still noticed even with the police issued silencer and at seeing the carnage the crowd does what crowds do, they stampede.

it depends on how densely packed the people are and how high the approach angle of the bullet is, at 45 degrees, in center mass, it's only grazing a foot or two before being at knee level lol.
