There are all kinds of computer-related offenses people can be fired for that are not related to porn.
For example, I’ve known two people fired from state agencies for using their work computers to do work related to outside businesses. IF, hypothetically, a programmer was selling Amway products on the side and was using his work PC to keep track of his sales and customers, he could be fired for that.
Or for using his computer to run a big fantasy football league. Or any number of non-sexual things.
To see if child porn is what would come to mind if a colleague were fired in that manner. This is what a number of people thought it was, because it made more sense than adult porn.
The belief that it was adult porn was bolstered by the “mo immediate arrest” thing. Perhaps the stuff was of a “marginal” character since the tendency is to advertise as “teens” any female on the low side of thirty. Plus there is the whole “Traci Lords” type of scenario in which an underage model credibly represents herself as being legal. If the guy was arrested five years later it may be that the initial download put him on the radar screen and he didn’t download anything illegal until much later, and perhaps then only inadvertently. (Not that the download was inadvertent, but that it was illegal.)
It’s my understanding (mostly from SVU and other such questionable sources) that most of the kiddie stuff that makes no bones about being that is only to be found through the so-called “dark web”. I do readily admit, though, that I don’t know any of this for certain.
