Officer Michael Slager was a bad apple, but not one good apple turned him in. Instead the rest of the apples recounted how they attempted CPR (they didn’t), and backed Slager’s account, until a bystander video exposed them all. Thanks to the video, Officer Slager is being charged with the murder of Walter Scott. Slager fired eight shots, the last measured and fatal, because a wounded arrestee could dispute his version of events. The takeaway for police in North Charleston might be that planting weapons on dead black suspects will no longer be business as usual, OR, if there’s a witness holding a camera phone you have to kill him too. Do you doubt that is not Officer Bad Apple’s one singular regret?
