Accordingto Khou.com, a group of police officers from the Coalition for Police and Sheriffs (C.O.P.S) reportedly assembled down the road from where Beyonce was performing as part of her current Formation tour, wearing t-shirts emblazoned with "police lives matter" and holding posters of Captain America.
The upset stems from Beyonce's video for Formation which shows a sinking police car, as well as her Super Bowl halftime performance in which dancers dressed as Black Panthers, which led some to believe the pop star is anti-police.
Beyonce has explained herself in an interview with Elle saying she has "so much admiration and respect for officers and the families of the officers who sacrifice themselves to keeps us safe".
"But let's be clear: I am against police brutality and injustice. Those are two separate things," she says.
Nevertheless, the group of C.O.P.S officers protested alongside images of Chris Evans as Captain America, with slogans like: "Local 911 supports the strong, the proud, and the brave".
