What is the worst crime/s you'ver ever been involved with personally?

By involved with personally, I mean a crime you have committed, witnessed, heard about by firsthand accounts like in court, in a police department, by the peope/person who committed the crime, or any other manner you can think of that enabled you to experience a crime firsthand.

Thank you in advance for your answers guys. I don’t ask many questions on Fluther. I’m not sure at any given moment what may interest anyone else. But I was interested in the question someone posted about the Caylee Anthony case here in Florida.

While watching some of the trial, I thought about this question.
