That is exactly the case. Multiple kinds of situations can come up, whether they start from whatever workplace issues may be going on, whether they're disciplinary with a supervisor or inter-employee debates and issues. We have had cases where arguments and/or events occurred that raised questions in terms of what people might have said during the heat of the moment, for example. That raises a flag in some cases, and has come to us. We've had some cases where someone may have seemed disturbed and not necessarily in a state of being able to apply security with provisions and to be confidently allowed access to the security zone. That's very rare, but it has happened in one or two cases.
Minor situations could arise in the workplace that raise a question. Somebody might have made a reference, or written something. It might have been a joke, or it might not, but questions are raised, so they are reported and they are all looked at. Then we have an advisory committee that brings together expertise—in some cases, it might be the RCMP and others—to give us a sense of how seriously they may see such an incident, or whether it's more like a routine type of operation.
