Yeah...but there is no "medical force" out there responding to someone tripping on whatever drug is out there. So the only person you can call, currently are police officers to deal with it.
Again, when folks were originally talking about "defunding the police" the bumper sticker took root; not the doctrine behind it.
We need mediators who can assess the situation and call an appropriate response...if the police go out there, the nature of the encounter automatically becomes adversarial instead of collaborative. So you get people being hostile toward authority. And, of course, the authority only gets worse in the eyes of the person being questioned....they bring out the drug sniffing dog, the back up officers, in some cases the SWAT team....
