Watching Return of the Jedi, and something grated on me for a moment. "It's an older code, sir, but it checks out. I *was* about to let them through." Surely the Empire would have better OpSec than this? ...oh, wait. Gigantic Enterprise-scale operation, driven by fear and tight deadlines, with lots of silos and mini-empires with a culture of internal rivalry for Dear Leader's favour? Never mind. It checks out; I'll let it through.
