Police officers standing in front of protestors

We checked in on the police officers behind some of the highest-profile police killings of the past 20 years. Some end up behind bars. Others get raises.

The police killing of Tyre Nichols in Memphis, Tennessee last month resulted in five officers involved being charged with murder and fired from the Memphis Police Department. 

Nichols's killing was notable for its apparent cruelty: Officers pepper sprayed, kicked, and punched an unarmed man to death. Footage from a nearby pole camera captured much of the assault, as well as officers standing around Nichols as he lay grievously injured. One detective took a photo and texted it to at least five others.
