TweetIf this guy is listening to sermons that preach the destruction of america, then that alone links him to extremist, terrorist groups. The message of Jihad against america is all over the internet...they can be completely brainwashed without leaving their apartment. These guys dont need to have phone calls or meetings with al queda to link them...Right now we have hordes of Islamic extremists living peacefully amongst us, waiting for their time to attack.
