I am making an educated guess that it was not, in fact, handled appropriately. Why? Because a guy killed a couple of people, tried to save the public from himself and was sent on his way to get to the cops.
What if he had stopped along the way?
What if, figuring out he had nothing left to lose, he decided to stop somewhere else and take out more frustration?
The freaking murderer was the one who ended up doing the right thing at the end of this story. So yeah, I think it's safe to say you can start with the assumption that it was not handled appropriately.
