The West Point military academy has launched an investigation into a group of African-American women cadets after a photo surfaced showing them posing with their fists in the air as they were set to graduate. The gesture was seen by some as a sign of solidarity with the Black Lives Matter movement; Tommie Smith and John Carlos raised their hands in a similar gesture, the Black Power salute, at the 1968 Olympics in Mexico City. But a West Point graduate who spoke with the cadets told The New York Times: “These ladies weren’t raising their fist to say Black Panthers. They were raising it to say Beyoncé. For them it’s not a sign of allegiance to a movement, it’s a sign that means unity and pride and sisterhood. That fist to them meant you and your sisters did what only a few people, male or female, have ever done in this country.” The photo showed 16 cadets—all but one of the black women in the graduating class of 1,000.
