This will get lost in shuffle, but Trump also pardoned a former Maryland police officer who had a horrific, and racially tinged, record of ordering her police dog to attack unarmed black & Latino men. https://www.washingtonpost.com/local/public-safety/trump-pardons-former-prince-georges-police-officer/2020/12/23/041eb13e-4589-11eb-a277-49a6d1f9dff1_story.html?tid=ss_tw
Officer Stephanie Mohr likely would have gotten away with it except for @RCastanedaUSN, a former Post reporter who wrote several stories about the out-of-control K-9 unit in Prince George's County, Maryland. Here's just one of his pieces on Mohr: https://www.washingtonpost.com/archive/local/2001/05/14/file-alleges-canine-officer-was-abusive/0f6ea57e-0f5c-4679-92ce-781b78a3cad1/
Mohr's supervisors knew about her record of brutality, but kept her on the job. Back in the 1990s, the Prince George's police had a terrible problem with excessive force and police shootings. It took many years - and numerous exposes by the WaPo - before things improved.
