Protesters on horseback rally against the death in Minneapolis police custody of George Floyd, through downtown Houston, Texas, U.S., June 2, 2020. Reuters photographer Adrees Latif: "A week after the death of George Floyd at the hands of Minneapolis police, tens of thousands of demonstrators poured into Floyd's hometown of Houston for an emotional and peaceful march to honor his life and protest police brutality. Driving into the city center, I saw thousands of Houstonians walking for miles to take part in the event. Many held signs and wore clothes bearing the image of George Floyd. As I raced towards the start of the march, I heard the distinctive sound of horses coming in my direction. With each trot along the brick-paved street, their approach echoed off the skyscrapers. A man wearing a red bandana with the words "Rap-A-Lot Records" took the lead in the procession, blocked the intersection and raised his fist in the air. Others followed in solidarity and before long, I was in the midst of a cavalry of Black Americans on horseback. With my senses overcome by the sounds, smells and splendor of the horses amid the towering buildings, I moved to compose and capture the moment before it was over. As quickly as the group appeared, the words 'Justice for George Floyd' and 'Black Lives Matter,' could be heard as the equestrians rode off into the distance."
