CIA Had 100 Afghan Spies Before 9/11 But Couldn't Stop the Attack?

Typical CIA bullshit:

WASHINGTON – A top former CIA official said the intelligence agency had more than 100 Afghans acting as spies before the Sept. 11 terrorist attacks, but told a magazine in a rare interview that nothing could have averted the attacks.

Cofer Black, the former head of the CIA's counterterrorism center, said that looking back, he can't think of a thing “we could have done that would have changed anything.” Black, a top executive with Blackwater Worldwide, the security firm, made the comment in an interview published in November issue of Men's Journal.

On the other hand, isn't he essentially saying it was an inside job? The CIA had lots of agents in the "right place", but still couldn't stop 9/11.
