Blamed for starting the virus while working

I am a railroad conductor for the MBTA Commuter Rail in Boston, MA. I was approached by two white male passengers on the train station platform, who asked why the trains were operating two hours apart. I told them that the reduced schedule was due to the COVID-19 state of emergency.

They replied, “oh right, the virus you fucking C****S started.” I responded by telling them to leave and that the police would be called. They walked away while shouting racial slurs and death threats.
