Your technocentrism approach to security is contradictory. On the one hand you say shoes shouldn't be checked with tech (even though there were many AQ/ISIS bomb makers trying to use the technique) and then you say modify lifts (at enourmous cost and dubious enhanced security - what about stairs? etc) to detect explosives. Reality is that the searches of peoples stuff was a heavy handed and unclear policy that the hotels didn't make clear to the customer so that they could have an informed choice. However a Mark 1 eyeball is in this case probably the most effective choice for a security mitigation.
