## Controversy over Confederate Flag

In June 2020, in the midst of national and international protests in opposition to racism following the murder of George Floyd, Gettysburg became the focus of controversy regarding the presence of the Confederate battle flag on the patch of the city's police department. The patch featured overlapping equal-sized U.S. and Confederate flags and a civil-war era cannon along with the city's name, in a nod to the city's namesake, Gettysburg, Pennsylvania, site of the famous battle. The historical reference logo for the police emblem and uniform patch was designed in 2009. George Floyd's uncle resides in Gettysburg and advocated for the logo to change for the two-person police force. The police patch and logo were removed in July 2020.
