A new investigative report is raising questions about accountability for alleged abuses and unlawful shootings by the Houston police. According to the Texas Observer, investigators have ruled that Houston officers were justified every single time in 550 incidents involving the shooting of a citizen or animal between 2007 and 2012. One of the slain victims was a wheelchair-bound man accused of attacking officers with a pen. Of 706 excessive force complaints, just 15 officers were disciplined. The Texas Observer concludes: “The message is clear: Either Houston police almost never abuse their power, or they abuse it with impunity.”
