I'm reluctant to be too judgmental about the guy who went AWOL. He may have been young, naive and unduly influenced by family and cultural pressures. He has been found guilty and justice has been done.
To digress somewhat, while I have no doubt the vast majority of Muslims do not support the Muslim lunatic fringe, it would be reassuring to see a bit more condemnation of the latter by the former. Muslim clerics, who have a good deal of influence on the followers of Islam, should be more vociferous in their repudiation of Islamic terrorism. Perhaps someone with a good knowledge of Muslim thinking could explain (without going off on a bigoted rant) why Muslim leaders tend to sit on their hands in this respect.
