According to Animal NY, an anonymous group called "Racism Still Exists" (RISE) has been erecting these posters (update: legally, and paid for) in bus shelters around Bedford-Stuyvesant, Brooklyn for the past five months.
The stop-and-frisk statistics support their protest.
52 percent of the 601,285 stops were of black people (Blacks make up about 26% of the City population), and of the 32,375 black people stopped for having a "suspicious bulge," exactly one was found to have a pistol.
685,724 stops were made in New York City in 2011; 88% of those stopped were not charged with any crime; 84% of those stopped were African-American or Latino (via MSNBC).
