"The one person not killed by 9mm had a small container of lead shot in his temple not recognised as coming from a firearm.
Slingshot perhaps? "

NO Keith - please read the autopsy report I quoted

Cegdet Kiliclar, 38 the photographer 'armed' only with his camera

"One gunshot wound: middle of forehead"

Dr Haluk Ince, the chairman of the council of forensic medicine in Istanbul, said that in only one case was there a single bullet wound, to the forehead from a distant shot, while every other victim suffered multiple wounds.
He added that all but one of the bullets retrieved from the bodies came from 9mm rounds.
Of the other round, he said: "It was the first time we have seen this kind of material used in FIREARMS.
It was just a container including many types of pellets usually used in shotguns. It penetrated the head region in the temple and we found it intact in the brain."

There are a variety of riot control 'non-lethal' weapons and rounds they can fire at crowds, although these are generally considered to be "less-lethal" rounds anything fired from a gun has the potential to be deadly if used contrary to recommended usage

These rounds are fired from a 40-mm gun -- either a single-shot launcher (for greater accuracy) or a multi-launcher that can have five or six rounds loaded at once.
The guns are similar to military grenade launchers
