Is the x-axis on the top plot lined up correctly? If so, it makes it look like 'Stop and Frisk' has no correlation with the murder rate. The Murder rate dropped dramatically from 1990 to 1997. It has been pretty flat since then (a slight downward trend). Stop and Frisk began ~2002 (based on the lower x-axis).
I was a Manhattan resident as a young man from 1982-88
There were precients then that were very black or Puerto Rican which often ran together even though then they fought a bit over dope turf and political rights
But looking at that map it seemes like whites have pushed them out...gentrification we called it then after the upswing post John Lindsay and Abe Beam
I know folks in Newburgh and Yonkers say the riff raff has moved further out...is that true
Now provide the sae graph for crime stats...
The stops by race reasonably closely mirror crime stats by race, so from my perspective, I say a 14th Amendment argument is bunk.
The 4th Amendement argument I am in complete agreement with, and am glad to see this happening. The reality is that this increase in freedom will be bought with lives. Murders will increase.
