joined now by richard engle and terror analyst. chard, give me a sense of how this guy got away from the terrible attack from november in paris, after 130 were killed. how he got away, supposed to commit suicide and all that. how long it took, and why so long to catch the guy. >> well, how we got away is he didn't go through with his attack. he was never supposed to have survived the paris attacks. the other attackers died while fighting against counter terrorism police, killing innocent people or detonating suicide vests. he had a suicide vest. he chose to dump it, and escape and was seen driving across the border, leaving france entering belgium. so he got away when there was still an opportunity for him to get away. why it took four months, critics will say it shouldn't have taken four months. because in the end, he went right back to where it all began. he went back to the molenbeek area, he met the master mind of the attack. and he went back to the place where he had contacts and friends. and i think it also shows how isolated
