I'll start with the notion of charges being laid, because that's something that comes up from time to time. In the accident investigation world it's really an anathema, because we're trying to figure out what happened and why and get to the bottom of it and look at the underlying safety deficiencies. So to find somebody and say, aha, this is the fellow who did this and he should be charged--that doesn't take us to where we need to go. Where we need to go is to figure out what was happening within that system and make recommendations to bring about the changes.
However, it's a complex world, and there are always a number of organizations, including police organizations, that may be working on the same set of facts. In terms of going step by step through the kinds of situations we might face in an investigation where there is also a suggestion of criminal activity, I'm going to turn it over to Mr. Stoss, because he's been on the ground an awful lot.
