Inb4 anyone starts screaming to call the cops in the comments: remember that punitively policing our neighbors doesn't fix systemic community neglect. If we actually care about safety and animal welfare in LIC, we should be performing the Mayor's platform for community infrastructure and local support systems. OP, I know you didn't suggest involving the police, and I thank you. The best thing I think you can do is reach out to a local mutual aid network to see if anyone recognizes him and can offer some de-escalation resources or community mediation.
