Derek Chauvin trial exposes trauma and survivor's guilt of witnesses to George Floyd's death

The opening days of Derek Chauvin's murder trial have included gripping testimony and evidence -- whether it's been reliving the moments that led to George Floyd's death, seen through body camera video of responding officers, or the emotional retelling of events by witnesses.

But one of the most striking themes emerging from the trial is the emotional trauma and survivor's guilt expressed by eyewitnesses, many of whom were standing mere feet away from Chauvin as he knelt on Floyd's neck and as Floyd took his last labored breaths.
