Just because corporate crime blends and is less obvious than shoplifting or vandalism (which beat officers are better able to catch), criminal activity like toxic waste dumping in water sources, embezzlement, and insider trading do involve local and federal law enforcement.
We tend to think of white collar crimes as more of the work of opportunists rather than a problem of poverty, lack of religion, lack of discipline, mental disorders, lack of education, or lack of a father figure. And certainly not a matter of race.
I was curious if you were thinking of civil court cases where an individual or group files a complaint to the local DOJ?
