The precedent HAS not been set because Obummer is the President now. A criminal act does not set precedent. If I rob a bank and get away with it, it does not set precedent for another robber to get away with it.
If by getting away with it, you mean no court will prosecute you for it even though they know about it, and no one arrests you; then, yes, I guess you would have set a precedent. Obama as Prez is a fait accompli.
