>one specific reason was the indiscriminate nature of the gas What are you talking about? The canisters launched by police are probably as discriminate as you can be when firing into a crowd. Are you expecting some sort of weapon that can precisely target the rioters in a crowd but leave everyone alone? >as well as the fact that it can cause unnecessary suffering. In the sense that "tear gas is just mustard gas", or "protesters have every right to be there and therefore any sort of discomfort is 'unnecessary suffering'"? What amount of "suffering" would you find acceptable?
