An AK-47 assault rifle once owned by terrorist mastermind Osama bin Laden is on display at a museum in Washington, D.C. Problem is, you'll never get to see it up close.

That's because the weapon is stored inside a glass case at the Central Intelligence Agency's (CIA) "secret" museum, according to NBC News, and visitors are strictly prohibited.

"I think for our people it's an acknowledgment that the hard work over that 10 years and partnership with other members of the intelligence community and partnership with the military was a success,” a spokesperson said. “This puts the punctuation point on 10 years of this agency and our intelligence community partners looking for bin Laden."
