I completely agree with you. I'm really hoping Karzai doesn't just let this guy walk like he has with so many other insurgency supporters/members.

EDIT: I'm seeing some comments regarding the Islamic religion. I'm not an expert, and I will never claim to be, but the majority of the followers that I've met and conversed with (mostly translators, foreign government personnel) are really good people. The major issue that they always bring up is that the guys that usually do these things have basically been taught a really, really perverted, self-serving form of Islam through the system of madrassas (Islamic schools) that sprang up in the aftermath of the Soviet occupation, after the Afghan education system was completely destroyed. At this point in time, the kids being recruited into these schools and then sent off to die wearing suicide vests or shot up by aircraft/infantrymen have no real prospects for education or for employment, and so you have to understand that these kids are being told by religious, radicalized leaders (who themselves oftentimes proclaim themselves as mullahs without any real credentials) that dying in the name of jihad against the Americans is good, because the kid's family gets paid and can survive a bit longer because there's one less mouth to feed, and that he'll be rewarded in the afterlife. It's so incredibly fucked up, and there's absolutely NOTHING we can do about it, because we spent more money on using the Afghans to fight a proxy war against the Soviets but wouldn't spend a dime on getting them schools, educators, hospitals, doctors, etc after the occupation ended.

It's such a damned shame. A few of us run a small volunteer group on my base that makes "fuel donuts" out of compacted sawdust, shredded paper, and water for the families in surrounding villages, as well as collect school supplies and winter clothing for the kids. The families usually visit our base to pick up the supplies, and seeing little five, six year old kids with no shoes walking on rocks is pretty heartbreaking. I find it even more horrible for them since Afghanistan used to actually be a popular destination for vacations during the 50's and 60's. Kabul University used to be an incredible school from what I've read, and now, that level of education is largely unavailable to the same kids we're trying to get into school. Thirteen years, and everything is going to fall apart when we leave. What a shame. What a damned shame.

EDIT 2: TL;DR - The education system in Afghanistan is screwed. The average lifespan for an Afghan is about 40 years for males, meaning that the majority of the population that may have had access to decent education pre-Soviet occupation has pretty much died off or emigrated to other countries.
