World's Dumbest... Subway Commuter at the 86th St (Lexington Avenue) Station

While I was waiting for an uptown Train to take to 125th St, some idiotic black dude with the blue-ish, purple-ish plaid shirt and a black bookbag jumped off the uptown platform and crossed through the tracks to the downtown side without taking the one stop up to 96th St and cross over to the downtown train. Lucky for me (and him), he was able to get himself up on the downtown platform before heading downstairs to the Brooklyn-bound platform. This is why there was suppose to be a law where platform screen doors should be added to every subway station in the 4 boroughs (elevated, open cut, at-grade, or underground), not only that, the guy who jumped down onto the tracks should have been arrested by the cops right on the spot.
