with these isis jihadis they get so pumped up before these attacks because they crave mart martyrdom. they have been craving this for weeks and months and believe they will go to heaven. they are still alive and crave another opportunity to go to paradise. they also know that every single european intelligence agency is looking for them. they got a lot of clues on who these people are. i think there's a lot of concern in the hours ahead we could see some attempted attack play out somewhere in france, somewhere in europe depending on where these people go to. >> the other question is how many more people in concentric rings involved in the planning of this. there's the driver who drove this vehicle away and the vehicle has been found, but where is the driver? how many other people are out there who helped them coordinate, helped them operate
