Potentially dangerous neighbor

My lovely coworker whom is an older woman, was venting to me earlier about her neighbor whom shes very terrified of. Apparently he messes with not only her, but other people in the neighborhood, specifically targeting hispanic groups. He threatens them, gets nasty and verbally abuses them, follows them around outside making them extremely uncomfortable. It’s gotten so bad that one family had to put a restraining order against him. My coworker herself is afraid to leave the house. Her yard worker had to quit because he wouldn’t stop harassing him. She calls the cops on him repeatedly, but the cops aren’t able to do much. Surely there is a way to get this to stop without getting lawyers involved. Im not exactly looking for legal advice for her, but if thats the only option, i guess she has no choice. Could they possibly contact the city council? Could he get marchman acted? Im honestly pretty unnerved by what she told me, as she’s an older woman who feels helpless. Maybe someone dealt with something similar?
