They weren't doing squat. That's like saying the U.S. sheltered Timothy McVeigh. The Taliban had no control over nor could they do anything about Al Qaeda. But they were much smarter than us and realized that.
The Taliban knew exactly where Bin Laden was and treated him like an honored guest.
McVeigh was captured within hours of OKC. Bin Laden had been carrying out attacks against the US for years.
There was nothing the Taliban could have done.

take a look at PAKISTAN and its "educational system"
