The FBI and most other places that try to define White Collar crime (WCC) are a bit clueless. There is no such thing as a white-collar crime, as there is not a White-Collar section of the penal code.
The term is a label created by criminologists to describe a specific kind of actor, circumstance, or a sub-category of crimes. It was specifically not coined as a term that could be used by the police or prosecutors because of what is specifically meant by the term.
Because the words seem glamorous, it has been stolen and incorrectly used by investigators and prosecutors who probably could not define the term. The mere fact that they think WCC means a crime is a pretty good clue that they don't get it.
Have a look at some scholarly resources that should provide you an idea about what WCC means and explain it in your own words-NOT from someone's definition, because honestly there are very few places that would steer you in the correct direction (the FBI is one of the worst offenders in this regard).
While explaining this in your own words, make sure to identify at least two and probably three properties, factors, or distinctions that are inherent in a WCC. This cannot be achieved by making a list of crimes that you think are WCC. Shoot for identifying what specifically it is about those actions qualifies it as WCC. (MINIMUM OF 1 Page)
