A car has driven through protesters at a vigil honoring a black transgender woman who was shot dead by police in St Louis. The memorial for Kenneth 'Kiwi' Herring turned violent on Wednesday night when a Mercedes driver drove into a middle of a crowd of protesters who were blocking the road. His car appeared to be attacked by the activists before he drove away leaving three people with minor injuries, according to the Riverfront Times. The driver was later arrested. People were gathered to honor the life of Herring, a 30-year-old black transgender woman, who was shot dead by St. Louis police on Tuesday. Herring was shot dead by a police officer after she allegedly stabbed him and a neighbor with a large kitchen knife.
