Obviously, the RCMP has to operate within the mandate and the law in order to deal with investigations involving potentially radicalized individuals. In most cases that information would come to the attention of police either through proactive investigations or through information that is received from individuals within the community, in some cases it may be family members and in other cases it may be individuals who become concerned by the change in behaviour of individuals.
When that happens and that information does come to the fore, there is normally a multi-agency response in order to do an assessment on the potential risk and on what actions can be taken to mitigate those risks.
For instance, one of the initiatives of the RCMP was to establish a national security joint operation centre, which includes various partners at the federal level, so that information of potential threats that come in can be quickly assessed in a timely manner in order to determine a type of strategy. That could be a strategy that involves a full-blown criminal investigation. It could involve enhanced monitoring or surveillance of individuals. Or it may involve community-based initiatives with intervention at the local level with community partners.
In terms of specifics for individuals working in the airport environment, the RCMP doesn't monitor on an ongoing basis individuals in the airports. We have to operate within the confines of the law and we're not a police state, so often we rely on other mechanisms.
I'm aware that the Canadian Association of Chiefs of Police has an aviation security committee. Most police agencies are aware that individuals working in an airport require certain security clearances. If information comes to their attention that an individual poses a potential criminal or terrorist risk, that is then referred to Transport Canada which can do a reassessment of that restricted access notification card. There are also other measures that Transport Canada has in place that can help mitigate that risk.
