For those illustrated souls that think you can stop violent deranged people from killing innocents with just a restraining order and a call to 911:

RIVIERA BEACH, Fla. (AP) — A man shot and killed his estranged wife and four of his stepchildren and then killed himself early Monday, but he spared his two biological children, police said….Police said there was a restraining order against Dell, who was in the midst of a divorce from his wife. He had gone after his wife with a knife in December, telling her “you will be going to the morgue,” police said.

He kept his word and now they are dead.
