As an Asian person I take special care. But some of these actions (e.g., acid throwing) just happens w dire consequences.
Before 2020, street violence was often linked with gangs but now they seem to target regular ppl. After Covid some incidents appeared to be related to mental health, but I'm not sure about it anymore. And it's hard to identify the perpetrators.
So. I now welcome security cameras. Put them up everywhere, please!! I don't feel safe traveling in NYC subway anymore.
