"New York City can move forward with a court-ordered overhaul of the police tactic known as stop and frisk after a federal appeals court Friday rejected an attempt by police unions to block the changes."
If this all happened before 2014, why did you cite the 90% black and brown people from 2017? Obviously, there was no injunction. The issue was probably whether NYPD has to produce written guidelines.
"On August 12, 2013, Judge Scheindlin ruled that the police department had violated the Fourth Amendment by conducting unreasonable searches and the Fourteenth Amendment by systematically conducting stops and frisks in a racially discriminatory manner.[8]"
The ruling means nothing without an injunction or other remedy. All we have from you so far is that she ordered a written policy.
