The year 2014 was an especially tumultuous year if you happened to be a black person or a police officer in the United States. The high-profile killings of Michael Brown, Eric Garner, and Tamir Rice revealed the continued high cost of existing-while-black in America, while the cold-blooded murder of New York police officers Wenjian Liu and Rafael Ramos by a mentally ill sociopath named Ismaaiyl Brinsley on December 20 has left New York City’s police force embroiled in a dispute with the city’s black community over issues of police safety and the NYPD’s checkered history with people of color. As the Big Apple’s police force tries to move forward in the wake of the brutal slaying of two of its own, the tensions between minorities and cops that so ravaged America in 2014 once again bubbled to the surface of the national consciousness.
