Why do airports own false wellbeing?

They have all this screening to spawn people feel safe and sound, but it doesn't actually do anything. I know people that own taken knitting needles, pepper spray, and pen knives on planes not long and havn't been detected.
Because people constraint it and government agencies have to be see to be doing something about perceived threats, even if they don't actually put together people safer. Airplanes are already the safest way to travel - at current catastrophe rates, you have to fly once a day for 30,000 years within order to get caught within a crash.
