That is a fair point which I do not have a ready answer for except that we have SWAT team stationed everywhere who are trained just for the purpose of dealing with such people.

Repulsive to you, but seen as necessary by others. China restricts people to remain in certain areas and force them to carry passes, kind of like the apartheid in South Africa. Yet if those practices were gone, then quite a lot of people in Chinese farmlands would want to come to the cities, which are already quite overcrowded. Its infrastructure would not be able to sustain such a large population.
It's an authoritarian action which is repulsive, but if it wasn't there, China could collapse, which would make a lot of life like hell.
So who's right here?

I don't want to convince you. Government needs people like you if there's to be any hope of change whatsoever. Shout loudly enough and the powers that be have to listen to you at some point.
If you force me to take a side on this issue, I will say that downtown may be on to something with using a public panels, although that comes with a wholly new set of cons and does not remove the underlying problem: blowing people up with hellfire drones.
