What it boils down to is why would a grunt have bulk access as opposed to one-record-at-a-time which can be audited?
Of what use would a computer data system be if it allowed you to only browse or search one file at a time? A filing cabinet full of paper lets you do that.
And lots of "grunts" are employed doing all sorts of menial tasks in record-keeping places. That he could do it shouldn't be all that surprising. The only problem is that he should've already been shot for doing so. THAT is what keeps people from doing it. :-)
