Today's shooting obviously will leave some physical scars, but those involved could have some emotional problems, as well.
Madison police spokesman Mike Hanson says killing someone, even when it's justified, is such a violent act, that it does take a toll on most people.
He says officers who do use deadly force, often deal with emotional problems long after the incident.
"It is something that they think about, not only when they go on similar calls, where their incident may have happened, but also something that they think about on a daily or weekly basis," said Hanson.
Hanson says the department does make professional counselors available to help officers deal with the event, immediately after it happens.
