Insight: Citizen-shot video has now shown police to have lied or misstated the facts in countless incidents, including a number of fatal shootings. It has tipped the scales, at least a little, away from blind deference to the police narrative. There has now been a questionable police shooting in San Diego. A witness has contradicted the officer’s account of the shooting. This would seem to be the ideal time to release the body camera footage. But the San Diego Police Department won’t budge.
