"Would you want to be hit in the head with a stone?"

It`s happened.

"Do you have any idea how big these stones are?"

As big as a human being can lift, I suppose.
If I was holding a rifle, I wouldn`t be afraid of a stone. And it is a stone; humans can`t lift and throw a boulder with enough force without mechanical means which they do not have.

"Tear gas is not a weapon, it is used to disperse crowds"

B`Tselem has documented cases of tear gas cannisters being shot directly at the faces of Palestinians causing eye injury and sight loss.
There is a rule that tear gas cannisters are supposed to be directed below the knees of people but B`Tselem has reports of many head wounds caused by the cannisters.
