Krumitz's investigation broke the law. - CSI: Cyber
Krumitz broke the law while attempting to get L0M1S arrested. Avery caught him after the fact, and had a serious conversation with him about right and wrong. Because L0M1S is underage, the prosecutor released her from custody, and Krumitz's illegal activities went unpunished. He learned a very important lesson, though–you can't hide anything from Avery Ryan.
