The Stop and Fisk law removes any reason for a city to address segregation and allow poverty to breed violence. It allows for "No Go Zones" in our cities. Problems have to be solved not simply swept under the rug. It is unconstitutional for lots of reasons, but, the city legislating 'no pain laws' removing civil suits is dangerous.
The USA has made a bad habit of changing Torts for the sake of political fodder. What it has done is allowed states like North Carolina to remove liability by Emergency Room staff all together. So, if one happens to be driving from Florida to New York via I - 95 and experience an auto accident in North Carolina; the chances of dying at the hand of an incompetent doctor in an ER is higher than in states with effective tort laws that remove shoddy practitioners.
