one is the question: if there exist a situation where the use of force is good, is teargas/cs gas a good way to apply that force instead of water cannons/ shields and sticks/etc?

This is the question I tried to ask before getting downvoted heavily.

The other question is if it is correct to use force.

(Or based on the amount of downvotes and weird answers I have got it seems more like some people think I support police brutality while other think I use the "think of the children"-argument.)
