1: It's Omar's parents that put him into that situation, so it's his parents' fault, not Canada's fault.
2: It's USA that put him into prison, doesn't matter it's right or wrong, it's not Canada's business; beside, he committed criminal and terrorist activity which he admitted and deserved the punishment.
3:As a guy of 16 years of age, not a child anymore, he should have developed his ideology system already by that time; there should be no excuse for what he did.
4:Even if it's Canada government's fault, the officials that were dealing with Omar's affair should take responsibility and be blamed and punished, not for Canadian tax payers to pay the price.
 5:Even if there was something wrong for putting him into USA prison, Canada government should sue USA government, rather than pay him out  at the cost of tax payers.
