For one of the first times in memory, police are testifying against one of their own. But will it lead to an actual conviction? I saw Chauvin murder George Floyd with my own eyes, and no amount of white cop-speak can gaslight me out of that reality. I can’t pretend to get inside the headspace of somebody who has an “open mind” about whether choking a black person to death on the street is a crime. On Friday, Richard Zimmerman, Chauvin’s former supervisor and the current police lieutenant, testified for the prosecution and called Chauvin’s actions “totally unnecessary.” On Monday, the Minneapolis Police Chief, Medaria Arradondo, testified for the prosecution against Chauvin, and said that Chauvin “absolutely” violated police protocols. Over the course of this week, the prosecution will put additional cops on the stand and offer evidence from police training videos, which will all show that Chauvin acted outside standard police procedure during his homicidal detainment of George Floyd. That fact that the Blue Wall is crumbling in the face of Floyd’s murder and the months and months of protests against police violence is significant.
