treated, and the potential for violence. to anyone who meets these criteria even if they're not homeless, the city will send treatment teams to them to help engage them in lasting mental health services. for homeless new yorkers, the teams could literally treat on the street. >> we literally have to revolutionize the way we provide care. >> the mayor's hope is to keep the treatment voluntary. though, city health officials say there are many options to commit uncooperative patients to psychiatric hospitals if they're believed to be dangerous. the plan comes amid-rising community concerns about homelessness. >> it's a shame. and i wonder what the circumstances are. and how they wound up like this. >> when i see them, i try to help them out, give them a dollar, here and there. >> in a poll this week, 53% of new yorkers report seeing more homeless on the streets. and disapprove of this mayor's approach. both mayor de blasio and his wife have said their parents suffered from mental health

issues. the mayor's father committed suicide. and he today insisted the city's approach must be compassionate. the plan will cost an additional re-train police on how they treat the homeless, which this news 4 is not well. matter, we're not human. no dignity. >> mayor de blasio says he hopes to break the cycle of repeat offenses committed by untreated mentally ill who could potentially pose a public risk. >> there is a huge intersection criminal offending. so treating the homeless like criminals is actually the wrong thing to do. treating the homeless and finding out whether homeless individuals have mental health issues is exactly the right thing to do. >> homeless advocates and city officials agree a very small percentage of homeless new yorkers are actually violent. since many street homeless also avoid shelters because they fear

they're unsafe, city hall is also planning to put extra security in shelters over the next few months. chuck? >> coming up next, news 4 continues, and an update on the wayward dolphin getting back out to sea. >> plus, an amazing story of how rare and extremely valuable violin was found more than three decades after it was stolen. and steve villanueva has your friday forecast. we've been waiting. >> we have been waiting. and tonight, parts of the area will start to see some rain showers. but what about your friday and the weekend? will we see improving weather? we'll talk about it coming up.
