Much of America is upset at the looting that has happened in the wake of George Floyd's murder by four police officers. Police have been using chemical agents of some sort — I keep hearing denials that these are tear gas, so apparently some other chemical, to disperse the looters.
You don't disperse looters, do you? Looters disperse themselves. Looters steal things and run away, right? Firing canisters of noxious gas at someone running away with a tv won't stop them running away. Police are supposed to be arresting people who break into stores.
