But I can spot what is different about this trial from all the other ones in which cops are tried for killing Black people. 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.
