A serious question about Fast & Furious

Why is it that the Justice Department has authority over whether a Justice Department will be prosecuted? Isn't that an obvious conflict of interest?

Barack Obama just needs to come clean on Fast and Furious. Even if the intentions were 100% honorable, it was an astonishingly stupid idea. Just admit it, turn over the relevant documents in the interest of being open with the American people and move on.

By the way, Obama promised to have an open and transparent administration? Looks like that is just another lie.
