The family was involved with, and trained with, the same Al Qaeda death-cult that pulled off the 9-11 atrocity, under the professional eye of their Taliban-supported leader, Osama bin Laden.
For the record, yes, there were bin Ladens in the USA, but they were not terrorists like Osama. In fact, Osama had been exiled by his country, and disowned by his family, in the years before 9-11.
As for the "hockey socks full of terrorists" we have living in our country, I am unaware of any terrorists who have taken up the sport of hockey. I do know, we deport or jail proven-terrorists we catch, instead of giving them safe haven and loads of government subisidies, so they can bring the rest of their families and friends over.
