* (If they were so inclined.)
There are hundreds of Egyptian students pursuing advanced studies at Canadian universities. CSIS knows who they are.
Most of them come from the elite of Egyptian society. Some of them come from the uber-elite with direct ties to the military leadership. CSIS knows who they are too.
So we play by Egyptian rules for a few days. Make a few arrests. Make a few phone calls;
"Hello dear parents of Egyptian student studying at U of T. I am very sorry to inform you that we have uncovered your son's very un-Islamic activities. As you may not realize, we take the viewing of certain images very seriously here in Canada, as you do in Egypt, Allah be praised! We are very terribly sorry for the burden of shame your little Abdul has brought on you... but for a small favour we can make this story go away."
That should do it!
