It has been established that there is an issue with the failure of human intelligence in ths situationand the right hand not knowing what the left hand was doing. The system currently does not allow for quick technical translation of real time human "storytelling",such as this guy's father telling on hi and that resulting in an immediate system wide alert and/or no fly order. Remember that in this case, a no fly order would have been fantastic,but what if the very same people just want to mess with the system and call in names on their adversaries? They can make the system fail that way too. Each day the 19 US security depts. received libraries full of information. I suspect most of it is useless garbage, so why not implement some practical changes. Blaming Israelis for not having the eyes of G-d isn't going to solve the system failure that will fail again. The fact is the person checking in this dude on a one way with no bags should be able to call security and perform a search.
