Witnesses, thanks very much for being here.
I want to start with you, Mr. Coulombe.
You appeared before a Senate committee on national security and defence. Afterwards, you issued a statement where you recognized some statistics regarding current intelligence on individuals. I believe that statement said that CSIS is aware of approximately 180 individuals who have travelled from Canada to participate in terror activities abroad. You're also aware of approximately 60 individuals—that has probably changed a bit—who have returned home from abroad. I have three questions on that.
Number one, why haven't these individuals been arrested? Two, are there ongoing investigations on those individuals? Three, what is the evidence threshold to detain them?
