No one could have known at the time how deadly this man Sami was, we're only just learning the truth about those that use our Nation and our Constitution to sabotage our freedom and our country. Many are just these tenured warriors of socialism and Marxism rooted in the nations universities where they are free to weaken the foundations of America with their frankly vile and hateful messages to our young people.
As a matter of fact, a lot of people did know, including (if some stories I've been reading are correct) the Secret Service, who advised against letting Al-Arian have access. Now the question is, who overruled them? They should be scrubbing White House bathrooms for the rest of the term.
Except the FBI and the CIA of course. This man had been on the list for 8 years, so someone knew.
The FBI did. He was on a terrorist watch list since the mid 90's.
