Shortly after the Sandy Hook tragedy, David Barton appeared on Glenn Beck's television program where he made the case that the Second Amendment was intended to guarantee to citizens access to any and all weapons that might possibly be used against them in the name of self-defense.  And since citizens might have to defend themselves from the government,  they were entitled to own the same types of weapons that the government possesses. 

Under Barton's logic, the Second Amendment therefore guarantees to citizens the right to own tanks and bombers and attack helicopters and destroyers and even nuclear bombs because that is what the government owns. 

But that seems crazy and he couldn't possibly mean that, right?

Wrong.
