Andrew Napolitano at Reason nails it:
It’s obvious that someone was out to silence Petraeus. Who could believe the government version of all this? The same government that wants us to believe that FBI agents innocently and accidentally discovered the Petraeus/Broadwell affair a few months ago and confronted Petraeus with his emails a few weeks ago is a cauldron of petty jealousies. From the time of its creation in 1947, the CIA has been a bitter rival of the FBI. The two agencies are both equipped with lethal force, they both often operate outside the law, and they are each seriously potent entities. Their rivalry was tempered by federal laws that until 2001 kept the CIA from operating in the U.S. and the FBI from operating outside the U.S. [ emphasis mine]
