But instead, the focus is on what people can see, so they feel safe.![]()
I sympathize, but you gotta admit, how else are people supposed to know that anything is being done? It's in human nature to want to feel safe.
I'd rather be safe than be a witness to a potemkin village designed to make it look like there's a safety program in place, but to each their own.
There needs to be passenger screening so that obvious hazards aren't taken on board aircraft - knives, guns, explosives and the like. A federal bureaucracy doesn't need to be created to do that.
Then again are you sure that the actual operation of the air port's security is actuall run by the government rather than the government setting the guildines?
