As has been pointed out, it wasn't the kids who were attacked. As should also have been pointed out, one of those missing is an FBI agent and I'm fairly certain whatever "safety" course we could provide wouldn't be as extensive as the training of an FBI agent. Things happen no matter how well equipped you are to deal with a situation. Morale is down because it's the holidays and people who are deeply cared about may be dead, definitely are missing and were definitely put through a lot of pain when they were attacked.

The only problem I see here is that you can't deal with the emotions you're picking up on, not that they exist in the first place.
