What if Omar Khadr was a white, middle-class American?

Here's a scenario:

James Jones, a 15 y/o, middle-class white American, leaves home by himself to fight coalition forces in Afghanistan, convinced by some radical ideas he's picked in during his teenage years.

Next thing you know, James Jones is taken by Canadian forces, brought to a military prison, and accused of murdering a Canadian soldier on foreign soil.

Imagine his pinkish face, on TV in a court room, answering to the crimes he's been charged with.
Imagine him holding on to a Mickey Mouse book, trying to sleep at night.
Imagine his fear as the child remains imprisoned for 7 years with murderers.

Would you deny his right to defend himself in a fair, internationally recognized justice system?

Would refuse that the child should be protected by international agreements such as the Paris Agreement, adopted by the United Nations in order to safeguard the rights and welfare of children during wartime?

Treatment of children accused of crimes under international law

3.6 Children who are accused of crimes under international law allegedly committed while they were associated with armed forces or armed groups should be considered primarily as victims of offences against international law; not only as perpetrators. They must be treated in accordance with international law in a framework of restorative justice and social rehabilitation, consistent with international law which offers children special protection through numerous agreements and principles.

3.7 Wherever possible, alternatives to judicial proceedings must be sought, in line with the Convention on the Rights of the Child and other international standards for juvenile justice.

3.8 Where truth-seeking and reconciliation mechanisms are established, children’s involvement should be promoted and supported and their rights protected throughout the process. Their participation must be voluntary and by informed consent by both the child and her or his parent or guardian where appropriate and possible. Special procedures should be permitted to minimize greater susceptibility to distress.

Why are we treating prisoner Omar Khadr as a war criminal? Why has he been imprisoned for 7 years when instead he should have been in school, studying, playing, loving?

Is it because he is brown? Because he's a muslim? Are we really living in a world where society accepts to jail children and deny them the rights we have promised to give them?
