Four high-risk travellers have been charged in absentia. As Chief Martin said, trying to collect the evidence of what foreign fighters were up to overseas is difficult in a theatre of war. We may collect evidence or be provided evidence, information, or intelligence, but this comes with a series of caveats that often makes it impossible to use. The fear is that the people who provided that information may have their lives placed in jeopardy, or that investigative techniques used by an agency may be released.
Oftentimes information is given the RCMP, which may turn it over to police in jurisdictions. Basically, however, it's kept in secret because of the caveats in place. Ultimately, if we do lay a charge against an individual, all this information that has been collected or utilized by the police of jurisdiction or the RCMP has to be disclosed in court. These are the hurdles that have to be overcome before we can have a successful charge. We have to look at all these factors and determine whether the investigation can stand on its own if we peel away certain pieces of information that can't be released in open court.
