come after we experience a trauma that are widely present, difficulty sleeping, irritability, memories, flashbacks of what happened, sometimes nightmares, sometimes difficulties relating to other people and a kind of distancing from other people. that's pretty much across the board with officers who were there and with officers who weren't there who feel bad they weren't there. when they see the videos of what happened to their colleagues, that's very distressing to them. so the distress continues. it's there psychologically, it's there in their physiology. it needs to be addressed. first of all, it needs to be understood, the consequences of an event like that. their difficulties need to be addressed, but not as a psychiatric disorder, not as a medical problem by and large.
