 NATO allies gathered in D.C. this week to mark the 75th anniversary of the alliance. A crime scene tech says she found live rounds of ammunition all over the Rust movie set after the cinematographer was killed. While on the witness stand in Alec Baldwin's involuntary manslaughter trial, Marissa Popple said the prop truck was disorganized and many of the boxes of real and dummy ammunition looked alike. Baldwin was rehearsing with a prop gun on the New Mexico movie set when the gun went off.
