No action after racist incident

I was a victim of a racist incident (spitting/racial slurs) under the awning of my own apartment building in NYC. Despite the apartment staff having seen everything (recorded in the video I took while the man was still threatening me), he didn't come out the door to help me or even address the assault. When I confronted the apartment management, they expressed no regret but just that "what happens outside the building is outside their control." And though there are Asian and other POC residents in the building, the apartment provided no warning to keep the residents safe. Since then I've not been feeling safe living in the building and asked to terminate my lease early, but they're refusing to, despite 4+ month heads up. It's hard to believe the incident would've been completely ignored like this, had it happen to a non-minority or even non-Asian.
