I have had two teenagers - at 12-15 years of age they "knew everything", could do anything, believed parents and teachers were "crazy", rejected the expected norms and for a short time behaved out of sync with their upbringing.  At 17 or so they returned to earth.  But Omar Khadr's family condoned and supported his treasonous behaviour in the ME...big difference!  I, too, wonder how and why this family was given the privileges and rights of Canadian citizenship - on top of the inexplicable, $10.5 million of hard working Canadian taxpayer dollars, plus the previous 9 years of tax paid court costs.  The entire affair stinks of missing information.
