(Of course we can discuss if most of the uses of tear gas are wrong, but lets for a moment think that we have a moment were we need to chase away a crowd of evil persons riotong and threatening to kill perfectly innocent children.)
But, we have de-escalation tactics, riot shields, smoke canisters, and literally guns.
If an officer wouldn't fire a gun, I think he shouldn't use tear gas.
I'd rather take that again than a good number of other unpleasant experiences.
Mentioned it in the same sentence as the use of actual guns seems to indicate that you either talk about a different kind of tear gas or that you don't know what you are talking about at all.
I'm not saying there isn't something worth protesting right now, but the timing is far from ideal.
