Those porcelain chopsticks are carried by Chinese men from Beijing 90+% of the time. Stopping Norwegians from New Jersey wouldn't be the best place to start.
I do agree its unconstitutional but the logic of searching blacks and Hispanics more often is sound.
Regardless of whether men from Beijing carry the chopsticks 90% of the time, you're only finding them .01% of the time.
You admit the policy itself is unconstitutional. It targets certain ethnic groups disproportionately, thus it's RACIST. If the numbers were better, then you could argue that there was some logic behind targeted searches, but as it stands it is literally just a program that violates people en masse while-statistically- almost never achieving its objective.
The actual numbers from NYPD stop and frisk program last year are about 192,000 stops uncovering about 400 guns.(Not incidentally, stop numbers have consistently and dramatically dropped each year since 2011 and crime still continues to plummet.) So, that's roughly 500 stops a day uncovering 1 gun a day. You can pretend that any illegal gun seized makes the program worth it, but just be real. Those numbers are piss poor and the program is a flop. If you had a high school with 1000 students and you searched each student and uncovered 2 guns in the search, it's debatable whether you have a particularly bad high school. If you are the police department for a major metropolitan city and you have instituted a program that systematically violates the civil liberties of your citizens with a program that allegedly focuses those violation on suspicious people who are statistically likely to commit crimes, and you're still only finding 1 gun for every 500 people you stop, then the program is SHIT!
