Why do black people dig up graves?

What kind of question is this? These happen to be greedy people who fortunately got caught because what they did is a disgrace. But to say "Black People" like only Blacks do this?? How do you know that other races of people aren't doing the same thing and just haven't been caught yet? I can't tell you the number of forensic files, cold case files and other shows I have seen where other races dig up bodies and place them in burning cars for a failed attempt at an insurance payoff or to attempt to start a new life. Not to mention the ones who do it just for kicks. Check your facts before you make stereotypical accusations with no foundation.
