When the police department in Sacramento, Calif., held a gun buyback event on Saturday, they didn't just give residents a no-questions-asked chance to turn in their unwanted firearms: They also gave out gift cards for gas.

The Sacramento Police Department said on Facebook that 134 people had dropped off firearms in exchange for $50 gas gift cards. The day's collections included at least one assault weapon, components of privately manufactured "ghost guns" and "multiple other illegally configured firearms," they said.

While the gift cards appear to have been an incentive – especially with gas prices climbing across the country – officials said they weren't the only motivating factor.
