Professional liar and fake historian David Barton has an extremely reactionary view of the limits of the Second Amendment. In short: There are no limits. The amendment allows people to own any weapon the government has, including tanks, missiles and fighter jets.
“The deal was you have a right to defend yourself,” Barton said. “So, the biggest weapon in that day would have been a cannon—hand’s down, a cannon. You’re allowed, as a citizen, to own cannons.”
“Whatever the government had, you could have,” he added, “because we might have to take on the government some day. We hope that never happens, but in case it does, we defend ourselves from anything that comes after us; whether it’s from foreign or domestic, whether it’s a gang, whether it’s a government, whether it’s a crazy uncle, we don’t care. So, for them, there was no limitation on what you could use or how you could defend yourself.”
