Police Misconduct : NYPD Stop and Frisk. Is it Bias? Can it be a form of Misconduct?

The NYPD also known as "New Yorks Finest" is The largest Police Force in the United States Of America. "Securing" the 5 boroughs of New York City, the NYPD has over 35,280 Police Officers and 4,500 Auxilary Officers.

The NYPD performed 575,304 "stop-and-frisk" patdowns last year, which is about 16 pat-downs per officer, the most since the numbers have been released in 2002. While it was an 8 percent jump from 2008, the percentage for each racial demographic stayed about the same. 55 percent of those stopped last year were black, 32 percent Hispanic, 10 percent white and 3 percent Asian.
Is it logical to say that the NYPD performs "stop-and-frisks" biasly? The Numbers my speak for its self. 316,417 of the 575,304 stopped and frisked are African American. This would mean that 9 out of every 16 pat-downs that each officer performed, was on an African American.  184,097; 5 out of every 16, were Hispanic. Many people would say that African-Americans/Blacks and Hispanics are primary targets of the NYPD.
