I was not fearing being locked up for anything that happened that day as I clearly did nothing wrong. And there was no requirement for me to subsequently report the problems with this technology as the operators had that duty themselves, being clearly aware of it. But there may have been a requirement for me to not report the problem publicly myself as the machines were presumably still in operation. Obviously "locked up" is a hyperbole, but presumably it's never worth the trouble to find out by how much. I personally find it humiliating to have a nudiscan in public, especially when it then falsely identifies me as having "concealments". Anyway the way this machine was being operated would contravene the new rules, and for good reason.
