The Bush Administration had a policy of not enforcing immigration law within the U.S. The result was their enabling of the 9/11 terrorists. The Obama Regime has the same policy and they almost allowed another 9/11. Hosam Maher Husein Smadi, a Jordanian Muslim and in the U.S. on an expired student visa was planning another 9/11, whether in connection with the other recent arrests in Denver, New York and Illinois is not known. http://www.wfaa.com/sharedcontent/dws/wfaa/latestnews/stories/wfaa090925_wz_studentvisas.1b7ce84f0.html
Smadi is an erie replay of 9/11, even being stopped by local police for a crime he should have been arrested for in any event, but any alien should have been arrested for as a matter of routine. A number of the 9/11 hijackers were similarly arrested for various traffic offenses and released. http://archives.cnn.com/2002/US/01/08/inv.hijacker.video/index.html It is clear that both plots could have either been stopped or stopped sooner had local police been required to inquire and hold aliens who have been arrested or cited for any offense. We were lucky with Smadi, as his plot was uncovered by the FBI, and not ICE by the way. However, Smadi's plot could have thwarted sooner by basic immigration law enforcement and ending the wall of separation between local agencies and federal immigration enforcement.
It appears though with the Obama Regime ending local enforcement, the likely hood of another terrorist attack in the U.S. will increase. This week alone four major plots were thwarted. Who knows what else is out there.
