This reminds me of the Runaway Evidence episode from the Ghost in the shell series. An employee with access to the codebase for a military weapons manufacturer manipulates it for their personal reasons
Indeed, this scenario is so ubiquitous that it will certainly continue happening as far into the future as there are human beings, for whatever definition of "human being" you can come up with. One of the first things I learned in the military was that many many things -- which are so shocking as to be almost unbelievable -- never see the light of day and become news stories. It happens so often that I would be willing to bet a hundred United States dollars that your local police department has some not-insignificant percentage of employees (think five or ten percent) that regularly use their patrol car computers for personal reasons, or quasi-personal reasons. I've met more than one police officer personally who genuinely saw nothing wrong with it. They think that it's harmless, or worse, that they're justified in doing so because their intentions are good.
