Advocates of gun control, critics of gun limits, historians, legal experts and plenty of other people as well have, for more than 200 years, tried to determine exactly what intent the Founding Fathers had in writing the Second Amendment.

A new public service announcement from the group States United to Prevent Gun Violence uses that history to argue that it would be very difficult for the Founding Fathers to comprehend the type of firepower that their amendment covers in modern times.
