In Missouri, a young boy named Ralph Yarl rang the doorbell of a home. He had gone to pick up his siblings. He accidentally went to the wrong house. The man inside, Andrew Lester, responded by shooting this boy in the head - and then, when he was down - shooting him a second time. Incredibly Ralph survived. The police took their time about charging Lester but after many protests he was charged. This is why people protest. Otherwise, nothing gets done.
