Wow, Indeed.

Hypo: What do you do if you are an assistant prosecutor in Texas and believe you have come upon evidence that indicates the defendant is not guilty (which you are now legally obligated to turn over), but your boss tells you to bury that evidence? Turn it over, right? It's the ethical, moral and legal thing to do. But in Texas, if you do so against your boss's wishes that person, who isn't necessarily the elected prosecutor, can fire you and there's nothing you can do about it.
