The main issue is the break-down of _trust_. See 20 years ago when I took planes, I could bring anything that was reasonable: water, shaver, shampoo, etc. and the security check was minimal. Now look at what is happening? We are treated like criminals: we are patted down, all things are stripped to go through bomb detector and metal detectors, a lot of times we need to take off our shoes and belts to go through the x-ray machines. Why?
Before we start to accusing others as 'terrorists', first step back and think: Why someone would sacrifice their lives to attack us? They are crazy people, some may say. But why we suddenly see so many 'crazy' people in the recent years? What caused them to be so desperate and so angry to the extend they want to waste their lives to do damages?
There are countless ways to cause mass damages in the modern societies, and unless we can understand the _rootcause_ of the attackers' motivation, trying to seal off all potential attack vector is no more effective than trying to remove weeds from ground without taking off the roots.
