Sophisticated in the sense that they worked. For the full night of June 11-12, they deceived the guards who made the rounds through the cellblock. Guards shining flashlights at sleeping prisoners, in the routine of a job they had done hundreds of times, did not stop to scrutinize the figures closely enough to detect the deception. The heads were designed not to pass close inspection but to pass routine inspection — the kind of inspection that generates familiarity and complacency over time, the kind of inspection where a figure that looks approximately right in dim light is processed as fine.
This is a lesson about institutional security that extends beyond Alcatraz. Routine makes observers less careful. The same scene, repeated night after night, creates an expectation that reduces actual observation to pattern-matching. The dummy heads exploited this. They did not look exactly like sleeping men; they looked enough like sleeping men that the routine check processed them as acceptable and moved on.
The 2018 decision by the FBI to create forensic-quality 3D replicas — investing laboratory resources and donating them to the National Park Service — reflects an institutional judgment that the original objects were forensically and historically significant enough to preserve carefully. The originals continue to deteriorate. The replicas carry the dimensional information that could, in principle, be used in any future forensic comparison, though what comparison they might support after sixty years of investigation has found nothing is not obvious.

## The Escape as an Institutional Critique
The June 1962 escape from Alcatraz was not primarily a feat of heroism or athletic achievement. It was an engineering project carried out in secret over six months by men who systematically identified and exploited every weakness in the institutional environment that was supposed to contain them.
