Cynthia White Died?

If you're old, you remember her.

What we remember is that an entire Tact team in 002 either went to jail or got fired (or both) while she skated after wearing a wire and testifying in court against them all. It was claimed she was rooting out a corrupt team, but team members said she was in on all of the corruption - she just flipped first.

The trouble is not only did she skate, she managed to get promoted to sergeant, lieutenant, captain (we think) and Inspector. That isn't because she was some super smart test taker. We think she held back just enough info on someone heavily connected and parlayed it into advancement

A more controversial figure would be hard to find.
