I've tried to work at places to try to change them, but it simply doesn't work. If it's an incredible uphill battle to try to get a group of people who don't want to unit test their code to unit test their code, I can't imagine it's easy to change, say, a police department. EDIT: And to clarify, I'm not saying unit testing is always necessary, but here it was. Their code was (and apparently still is) buggy and needlessly convoluted with no clear documentation.
