Because he had a large, powerful terrorist organization (which has accepted his death, BTW) that they are currently conducting operations against and don't want to tip off, would be my guess.
Because you can't indict people on classified material without making it unclassified, and he was already wanted for a previous bombing. This was explained. In the post you're responding to.
What do you mean "maybe"? I've told you precisely that twice already! National security concerns! Indictment! asdfg;rweoh
It doesn't seem the slightest bit weird to you, he wasn't listed for 9/11 on the list. Besides if all the info is classified...how come you guys know so much about the evidence, to not even consider something else? As you say every bit of evidence points to Bin laden...but yet it's classified.
