Bin Laden is dead, and overall this is a good thing. But deep down, I wish he would have survived and that we had captured him. Sure he deserves death, but I think we could do better than that...
What I imagine is a prison cell in New York, as close to ground zero as possible. There he would receive the best medical care that our western technology could provide. I'd want him to live a long long time. Partially this would demonstrate to the world that we treat even our enemies with human dignity, but mostly because I want him to stick around and see how badly he failed.
In his cell would be 24 hour live feeds of Al Jazeera and a camera pointed at ground zero. The Al Jazeera feed would let Bin Laden see how the caliphate he dreamed of wasn't going to happen. That though there might be revolution it would never take the form he'd hoped for.
The ground zero feed would show him that in the long view, he was a blip on the radar. That there would be a building there to replace what he destroyed, and it would last for generations as a symbol of what he could not destroy. He'd see, day in and day out, people going to work, living their lives, and moving on past the terrible atrocity he unleashed. Yes, he could destroy a building, and kill thousands, but in the end, we just made a new one.
In addition to these feeds, every day at the same time, he'd be scheduled with a visitor. The visitor would be some victim of his violence, be they a direct victim, or the families and loved ones of those who died. They would come and they would tell him of their pain. It would all be done through a window that would only allow the victims to speak to him, not the other way around, and he'd just have to sit there and listen to all of it.
That would be his fate. Hopefully he'd last a good 20 or 30 years, every day filled with this reminder of the pain he caused and how he failed. I think that's appropriate. Death was too easy an out for him.
