An interesting CBC article 'Who are the most wanted extremists in Canada?' using open source material, then wonders why Canada does not have a public 'Wanted' website unlike those in the USA, notably the FBI's:http://www.cbc.ca/m/news/canada/who-...nada-1.2845186

Within are two useful quotes for this thread's theme. First by a Canadian Muslim who became an informant on a terror plot:
They are missing public input...In this particular context it’s not going to be a police agent at a border point that’s going to pick the individual up. It’s going to be somebody who says ‘Hey, I know that guy.’ That’s how the information is going to come. I think there is a stronger case for making the information public.
Then a former FBI agent with a JTTF:
For any law enforcement organization your best asset at your disposal is the general public... Whether it’s an anonymous lead or somebody seeing a wanted poster and possibly motivated by the reward money - it’s to elicit help from the general public.
