Most of our security systems are designed to find the weapon. El AL/Israeli security isn't. It's designed to find the bomber. Some call it profilling, it isn't really. "Profiling" in the liberal touchy-feely context is racially biased. "It is a black/latino/caucasian..." The Israelis don't care about skin color it's 80% what the individual is doing. "Does not make eye contact, nervous/sweating, labored breathing, dialated pupils..." There is a small part that singles out physical description "20-30 y/o male, Arab" but that is based in historical data that NO ONE would dispute. The other thing is that EVERYONE is taught early on what signs to look for, not just security types (is there anything else in Israel?) The bus/taxi drivers, shop owners, and Rafi the paperboy know that if they see something out of place to calmly vacate the area and call the police. We'd NEVER get to that point here. To many people with their noses buried deep in thier KIndle/IPad/cell phone. They can't be bothered with personal security, it's someone elses job. Never happen here.
Is it an IPad or the sand....
