1.  What most don't understand, the bigger mistake was canceling the Avro Jetliner by CD Howe and the Liberals in 1951 even though TWA (Howard Hughes) wanted to order 30 which would have started a new industry.  The number of jobs lost with a Boeing type company in Canada boggles the mind.
2. But back to the article, it may not be politically correct but Omar was raised by Al Qaeda supporters, his sibling are Al Qaeda supporters, Omar's transcripts before he came back to Canada defended & supported his family.  
3.  Without a doubt Omar was with Al Qaeda supporters when he was captured.
4.  I also do not agree with the argument he was a "child" soldier but many disagree.
