One of my first jobs had a client who ran speed cameras for a state. On top of nothing being secure the guys there said to me that the amount of "traffic" always seemed to increase, I felt dirty just talking to them. One dude I ran into later at another company said he started looking for a new job as soon as he figured out their game.

The company got in trouble supposedly due to anonymous tipsters who knew some inside info to some news stations (for the record no it wasn't me, I didn't have anything).

At least some folks made good choices.
