You have the power to solve mysteries, criminal or not. Forensics experts have been involved in some high-profile cases, especially those cold cases being reexamined because of new evidence or new technology.
For example, history tells us that Napoleon Bonaparte died of stomach cancer. But then, someone came up with the idea that Bonaparte died of arsenic poisoning (ooooh! foul play!). Ultimately, the poisoning theory was debunked, and it was back to the stomach cancer theory.
But hey, it's not the destination, it's the journey -- at least in some cold cases.
