“The Back the Blue Act would make any assault on an officer a federal crime with a mandatory minimum sentence. But here’s the thing: assaulting a police officer is already a crime in every state and already carries strict penalties set by local legislatures.” The placing of persons under arrest inevitably generates some ambiguous or factually uncertain instances of the closely related offenses of resisting arrest and assault on a police officer, and the concept of assault itself is independent of any infliction of actual injury. Pulling broad swaths of this law, and then subjecting the whole thing to mandatory minimums, is unlikely to improve matters. (The bill has other provisions too.)
