White collar crimes consist of various acts, such as computer crimes, tax evasion and securities fraud. In many cases, these crimes span over the course of weeks, months, and years, and can involve complex techniques to not only commit the act, but hide it as well. Securities fraud, for example, can come in various forms and usually consists of the fraudster providing false information to investors.
