KingCast observes: Police everywhere in New England can pick up shell casings and destroy the integrity of crime scenes without material consequence.

Read it right here with respect to Concord, NH Sergeant Steven Smagula, who shot Officer Joshua Levasseur at a closed credit union during some impromptu "training session" after midnight, then removed the spent casing from the scene prior to photography or drawings could be rendered.

Consider this before you click over:

Officer Deadly Force Policy IV B(f): “Ensure that guns are not opened, loaded, unloaded, shell casings removed, or in any other way tampered with….”

Now how hard is that for a trained Sergeant or experienced LE (or even a cadet or a trained dog) to remember?
