 The Iowa Attorney General's Office says three Cedar Rapids officers were justified when they shot and killed a man in April, as well as shot a bystander. They were responding to reports of a man having a mental health episode. Officials say David Vanderham made several 911 calls requesting officers come to his home. He said he wanted to kill them all. When officers got there, they say he started yelling and pointed what they later learned was an airsoft gun at them.
