On Twitter this morning, an ex-Baltimore police sergeant named Michael A. Wood detailed a litany of abuses he witnessed or participated in while on the job. Even if your faith in cops to do the right thing has been completely demolished over the past several years—or if it was never there to begin with—you’ll almost certainly find something new that turns your stomach.Wood’s tweetstorm comes in the wake of Freddie Gray’s death by spinal injury in the custody of Baltimore police in April. Gray’s death forced the Baltimore police into the national spotlight, but the department has a long history of abuse, particularly against black and low-income Baltimoreans. Wood—who served in various roles in the police department between 2003 and 2014, according to his LinkedIn profile—provides the gruesome specifics of that abuse.Presumably, he means CCTV cameras “turning off”—so they don’t catch the violence the cops inflict when they catch up with their suspects.Shitting on people’s clothes!That is, lying under oath in court and in probable cause affidavits that he saw a person drop controlled dangerous substances—drugs—while chasing them.Asking people who weren’t present at the scene of an incident to lie and say that they were on a probable cause affidavit, which Wood and his colleagues could later use to obtain a search or arrest warrant.A ploy to collect extra money for your colleagues as they would gain overtime pay from meetings and trial appearances.Scrutiny of BPD practices intensified following the death of 21-year-old Freddie Gray in April as a result of injuries he sustained while in police custody.Gray was placed, handcuffed and with his legs shackled, in the back of a police van after being arrested on suspicion of possessing a switchblade knife.Official autopsy reports released on Tuesday by Maryland's medical examiner to the Baltimore Sun reveal that Gray died from a single "high-energy injury" to the lower left side of his head, likely when the van he was riding in stopped short and made him fall.The six officers who arrested him were charged in May by State's Attorney Marilyn Mosby, who said the officers were not only negligent, but also "failed to establish probable cause for an arrest" in the first place.Giving detainees "rough rides" in the back of police vans following their arrest is a BPD practice that has been noted before: “Very fast, wide turns, braking short — they were doing everything they could to make the ride as bumpy and chaotic as possible,” Christine Abbott, a 27-year-old librarian at Johns Hopkins University who is suing Baltimore for injuries sustained during her rough ride, told the LA Times."I was just sliding around in there."Protests surrounding Gray's death quickly descended into chaos in late April, with the situation growing so violent that the governor of Maryland declared Baltimore to be in a state of emergency and called in the National Guard.May was Baltimore's bloodiest month in 15 years.
