"An undated photo shows a sign posted at the Science Museum of Minnesota's ""Race"" exhibit mentioning Philando Castile, an African American man who was fatally shot by police in Falcon Heights during a July 6, 2016, traffic stop. Castile's shooting and other recent incidents prompted protests over the relationship between police and minority communities. The St. Paul museum has now removed the sign after Facebook commentators suggested it was disrespectful to law enforcement. (Photo courtesy Black Lives Matter St. Paul)."
