Even modern buildings need proper security. I once worked in a building where you had a pass operated stainless steel turnstile allowing entry into a razor wire encircled compound, you were then subjected to the real security, far more stringent than any airport. I was always struck by the signs on the gate. No smoking, No cameras, No guns.

Remember lax security enabled the murder of Airey Middleton Sheffield Neave, DSO, OBE, MC, when he was blown up leaving the house of commons..

Some here apparently take a frivolous view of security. They are lucky to live in a country where such concerns generally do not impact the general public. If only other countries offered a similar degree of safety.
