If an airplane carries 250 people and a train carries 250 people, why is the security on airplanes so tight and almost non-existant on trains?
Overdone security only affects our personal freedom. We are not safer, this is a dangerous illusion. We do not need to fear a stupid terrorist. But a clever one will always find a security problem and exploit it. If airplane security actually one day become too much too handle, they will strike elsewhere. Trains, boats, hospitals, shopping centers, schools, etc… The list goes on.
