That is a fucking disgrace.

A police officer should only ever get any award to that effect if it was inflicted by an armed enemy of the United States conducting actions intended in some way or another to bring about the downfall of the United States.

Killed or seriously wounded by a criminal's actions in the line of duty? Okay, sure, something, a blue shield perhaps. But a purple heart? No, not from criminal actions, not from the thunderfucking actions of your thunderfucked pals in blue.

That is for Americans who have met the enemy in combat and taken fire. (There's a reason soldiers refer to it as 'The Enemy Marksmanship Badge'.) Not an opportunistic or desperate criminal.
