Black Lives Matter activists held demonstrations in at least half a dozen cities in the U.S. over the weekend, including in Houston, Texas; Springfield, Missouri; Apopka, Florida; and Asheville, North Carolina, where seven people were arrested after a sit-in at police headquarters on Friday. The demonstrators staged the 30-hour sit-in to demand answers in the case of the fatal police shooting earlier this month of a 35-year-old African-American man. Police say the man was carrying an assault rifle. His family has hired a lawyer and questioned whether the shooting was justified.
