I'm in Melbourne and this kind of shit is why I think I really can't go to protests. I'm autistic and passionate about advocacy (I work in the industry). I can keep my cool pretty well in verbal exchanges but I would lose it, meltdown if I saw people being treated like this. And then I would probably be assaulted myself.

Disgusting treatment of disabled people. You should report that library security too. They are scaring disabled people into silence - especially in public protests.
