Okay, thank you.
I know it's an important aspect of what's happening and I believe both you and Professor Davies talked about how things are changing rapidly in terms of what we're seeing from these jihadists, these terrorists.
Professor Mansur, you're a Muslim and a known supporter of those who want to tackle radicalism and make sure it doesn't sneak its way into Canada. Although these people, we know, are already here in some cases, we also know that the radicals from abroad have ways of impacting Canadians and having influence in convincing them to become radicalized. We're in the Twitter era now for spreading evil propaganda to the world.
I wonder if you could say why CSIS is necessary to address these realities we face in our globalized world.
