Amen!
I have seen doors that have had thousands of dollars of electronic security devices on them that could easily be compromised by slipping the latch or forcing the door. Gates where you can easily reach through and unlock the gate by operating the inside latch. High-security rooms where you can lift a ceiling tile and either climb over the wall or reach down and unlock the door. On so on and so on...
I check for this type of thing on every assessment that I do and rarely find a facility without at least a few weaknesses of this type.
As a side note, Sneakers was one of the few movies that I know about who used a real security consultant as a part of the production team. John Strauchs was a technical advisor on the film and provided guidance to the writers on the security systems.
