He almost certainly was just too lazy or too stupid. I don't mean unintelligent here. I mean that he didn't give it enough thought, either because he is lazy, or because he didn't know he should have been more careful. The technology those people use isn't magic, and for someone on the inside, it is completely trivial to circumvent. It can't have just been a matter of misjudging the technological capabilities of his peers. And I completely agree that he has probably been dirty for years and years and only recently got caught. People are either dirty, or they're not. I have a very hard time believing that people can slowly become dirty cops over time. That kind of moral compass is hard to recalibrate outside of some kind of psychological trauma. I mean, based purely on anecdotal evidence, of course.
