They’ll uncover just enough in attempt to clean up direct ties to this specific event. While Art is talking up body cameras, less no knocks, reviewing narcotics ops and etc, there is no way in hell that he’ll be “digging” outside the lines in any substantial manner. He’d have to shut down the narcotics division in short time. This is a common practice to varying degrees and this event just really got away from the cops(the heroin find/disclosure) and negated their usual “get out of jail free” card narrative deployment. Getting shot up before making the plant, and the other cops gaffing on the heroin find in goins car was either a fluke, or Goines being too confident in the proven method and just never believed he would go down. Regardless, this is pretty much excepted procedure for a LOT of narcotics cops across the country. Believe it or not they share various dodgy tactics during get togethers during various official “Police (tactical) Games” across the nation. They generally keep it quiet when interacting with tactical forces from other countries during the World Police Games. Most cops would never go this far, but even the best of them will turn the blind eye before putting their job and safety at risk...because the bad cop is usually cleared and he and ton of other concerned cops won’t be forgetting it so easily. And their wives, if they have a family and a pricy mortgage, will usually flat out tell them- “Fuck no you are not!”
