The father of a police officer killed by a sniper in July amid major protests against police brutality is suing the Black Lives Matter movement for its “war on police.” Enrique Zamarripa is also suing the Nation of Islam over the killing of his son, Dallas police officer Patrick Zamarripa. Zamarripa was gunned down along with four other officers in July, when the public’s attitude toward police was at an all-time low amid a spate of fatal police shootings. Although Black Lives Matter did not organize the Dallas protest during which Zamarripa was killed, the group was perhaps the most well-known organization speaking out against police violence at the time. Enrique Zamarripa filed his lawsuit against the group earlier this week in the in the Northern District of Texas federal court. He is represented by Larry Klayman of the group Freedom Watch.
