Back in the day people (myself included) used to comment on wild protests held by Jews and would say that the police should shoot, if they feel threatened, if things are getting out of control. Not to kill, but in the air, at legs or at property in a very bad situation. Just like they do at Arab protests. I remember when I went to Hebron, probably for the first time, as a yeshiva student, a soldier told me that they shoot at the tv antennas on the roofs and at the water tanks on the roofs if they need to get the Arabs under control because that means they need to spend money to fix and replace the damaged tanks and antennas. Once it costs them good money, especially more than once, it reins them in.
