I thought body cam footage was public data, discoverable and releasable under the law.

There is no one left to prosecute here since they killed the shooter so there is no reason to delay disclosure.

That thin blue line looks more and more like a line for cowards to hide behind while they seek to escape accountability for actions they know would have them arrested if they had no badge. Simply holding their noses while a colleague escapes prosecution for criminal acts by hiding behind a badge or a brotherhood of LEO is about as chickenshit as it gets.
