Uvalde’s city and school district police departments have stopped cooperating with a state-led investigation into last week’s school shooting, according to ABC News. The report is the latest left turn in state and local officials’ floundering and often contradictory attempt to explain why officers present outside Robb Elementary School on Tuesday didn’t immediately move to take out the gunman who killed 19 children and two teachers. The two police departments stopped speaking to investigators soon after Department of Public Safety Director Steven McCraw held a Friday news conference at which he said police made the “wrong decision” in delaying their entry into the building, ABC reported, citing sources close to the investigation.
