It's just new tech for quite an old thing - what is the difference between a policeman firing teargas from a gun (which happens everywhere, not just in Israel) and this? You can make the case this actually reduces the chance of severe violence since the police don't have to come close.

This version is even less personal, divorcing the perpetrators (popigs) from their actions against civilians.

Probably better to have it less personal, every time police comes into close contact with rioters bad stuff happens.
