WARNING: STRONG LANGUAGE
This body cam footage comes in the wake of suspected police brutality in a number of other cases, but it's clear this officer did what he had to do. When a suspected murderer is coming at you with a knife, you have to defend yourself.
After reviewing the footage, the Glendale Police Department decided the same thing and Officer Hilling won't face charges for his actions.
