Richard Clarke is not your typical conspiracy buff. He served as the head of counter-terrorism under presidents George H.W. Bush, Bill Clinton and George W. Bush.

Clarke became famous after warning the Bush administration in the summer of 2001 about a possible attack on the United States by Osama Bin Laden.

While that warning was ignored by the Bush White House, Clarke's recent statement about the death of reporter Michael Hastings is making news.

Clarke recently told The Huffington Post that a single-vehicle crash such as Hastings' recent car crash is "consistent with a car cyber attack."

"What has been revealed as a result of some research at universities is that it's relatively easy to hack your way into the control system of a car, and to do such things as cause acceleration when the driver doesn't want acceleration, to throw on the brakes when the driver doesn't want the brakes on, to launch an air bag," Clarke said. "You can do some really highly destructive things now, through hacking a car, and it's not that hard. So if there were a cyber attack on the car  and I'm not saying there was  I think whoever did it would probably get away with it."

Hastings crashed a 2013 Mercedes into a tree on Highland Ave. in Los Angeles at 4:30 a.m. on June 18 (video below).

According to the Los Angeles Times, Hastings was writing on a story about a lawsuit filed by Jill Kelley, who exposed the affair of Gen. David Petraeus.

Hastings told the news site BuzzFeed that the FBI was investigating him, but the FBI denies that accusation.

"I'm not a conspiracy guy," Clarke said.  "In fact, I've spent most of my life knocking down conspiracy theories. But my rule has always been you don't knock down a conspiracy theory until you can prove it [wrong]."

He added: "In the case of Michael Hastings, what evidence is available publicly is consistent with a car cyber attack. And the problem with that is you can't prove it. I think you'd probably need the very best of the U.S. government intelligence or law enforcement officials to discover it."
