That is like asking how come Hubert Hoover didn't stop Pearl Harbor.I'll ask you again, special needs. Why did Clinton do NOTHING to stop 9/11 if he was POTUS And knew it was going to happen in time? Does that make him complicit or not?
He didn't stop it because by law he could not be the POTUS after Jan 20th 2001.
And because the people who perpetrated it weren't even in the country when he was in office.
