If Danny Simpson had known more about guns, he might not have needed to rob the bank. But in 1990, in Ottawa, Canada, this 24-year-old went to jail, and his gun went to a museum. He was arrested for robbing a bank of $6,000 and then sent to jail for six years. He had used a .45 caliber Colt semi-automatic, which turned out to be an antique made by the Ross Rifle Company, Quebec City, in 1918.

The pistol is worth up to $100,000—much more than Danny Simpson had stolen. If he had just known what he carried in his hand, he wouldn't have robbed the bank.

In other words, Danny already had what he needed.
