David Simon and others have written extensively for decades about the problems with the Baltimore Police Department, and other departments around the country. They trace these problems back to the war on drugs and other purely American factors.
The Amnesty article that you're citing is a post hoc ergo propter hoc fallacy. The Baltimore Police Department did not need to learn about constitutional violations from the Israelis.
Everybody thinks the War on Drugs is about "keeping people safe". It never was, it was always about manufacturing a tool to oppress "others".
from that lens it was almost necessary to invent a pretense since people got all huffy about overt oppression at the end of Jim Crow.
