United States police officers take an Oath to defend their Constitution - but their more colloquial vow is to Serve and Protect. That is precisely what former cop Jerry Cassaday believed he was doing when he shot and killed Bruce Miller. But Cassaday wasn’t upholding this vow - he had killed an innocent man. He was acting on the coercion and manipulation of his lover and Bruce’s wife: Sharee Miller. Three months later Cassaday would turn the gun on himself.
