The new policy will order its federal officers to intervene if they see any officers engaged in excessive force and to administer medical aid injured by police.

“Officers may use only the force that is objectively reasonable to effectively gain control of an incident, while protecting the safety of the officer and others,” the memo stated. “Officers may use force only when no reasonably effective, safe, and feasible alternative appears to exist and may use only the level of force that a reasonable officer on the scene would use under the same or similar circumstances.”

Which part of these "elaborately vague" rules are you worried about being used to target conservatives for maiming and killing?

Here's the whole memo, for reference.
