It's a supposed pilot program in just two neighborhoods of 100's (which haven't been formally announced) pie-in-sky supposed to start in Feb.

BUT the main thing is if a weapon is mentioned in the 911 call or just "imminent risk of harm", police will still go:

In emergency situations involving a weapon or imminent risk of harm, the new Mental Health Teams will respond along with NYPD officers. 

which only makes sense because not only are a of  a lot of police are already trained in nearly the same thing

 Over 65% of all operational staff in NYPD patrol precincts across the City have now been trained in Crisis Intervention Team training, a state-of-the-art approach that continues to improve the way officers recognize and respond to behavioral health problems experienced by people they encounter. In all precincts other than the two precincts selected for this pilot, NYPD officers and FDNY Emergency Medical Services EMTs will continue to provide coordinated responses to mental health emergencies.   

but the EMS doesn't want to go out on such calls without police along without getting a lot more pay for the risk they are taking

Oren Barzilay, president of FDNY EMS Local 2507, said security for his members, “as well as fair compensation for the new and extraordinary risks they are being asked to take” needs to be addressed.

Overall, seems to me a b.s. p.r. by the Mayor's office to mollify BLM activists ESPECIALLY since HORRIFIC shit like this is going on, there aren't enough social workers and psychologists where they traditionally work (and no money coming in to keep paying those much less the few left on the payroll):

Really does sound like B.S. As in: not really going to happen!  Like most things the mayor's wife (nepotism anyone?) comes up with. Or both of them: all hat, no cattle, ask a majority of NYC citizens, ask Cuomo what they promise and what they accomplish. EMT's will say no way without more pay and it will be over.

Domestic violence and domestic disturbance are some of the most dangerous situations there are, it's not going to be easy to find people wanting to go on such calls without police protection.

If it's not an emergency they are not supposed to be calling 911 in the first place! They are supposed to be calling 311 (a Bloomberg innovation, by the way) and other kinds of help are supposed to be dispatched from the appropriate department. I.E. child welfare for child abuse. But these are not normal times, those departments are not operational, people are still working from home if at all. Nobody is in those offices and there is little money forthcoming to pay them.
