On a non-related note, years ago the "Whose turn is it to carry the gun today?" was a running joke among those of us who encountered members of a certain government bur...agency regularly.
It got added fuel when a bank robbery occurred right in front of two who had not worked out the daily gun carry, neither had their handguns on them, and both were forced to watch the show along with everybody else in the place as it progressed unhindered.
At my own department, when we'd do firearms training that involved drawing from the holster we normally carried the sidearm in, there was frequent pointed "joking" about requiring a couple of the detectives to draw from the briefcases they normally carried their guns in. In one case, even drawing from the car one guy carried his gun in, since he never had it with him outside of the car.
