According to Detroit police, a gang of middle-aged grandmothers nicknamed "The Mad Hatters" is responsible for a crime-spree involving fraud, purse-snatching and a slew of other robberies. The ladies were dubbed "hatters" because of the fishermen hats they've been reported to wear during the incidents. Records indicate that the group has stolen over $500,000 worth of merchandise and cash. One recent robbery at a bank totaled nearly $200,000 alone! Wow, guess if anyone comes in contact with these ladies, they should be considered "old" and dangerous!
