Gun buy-backs are designed to get weapons off the streets. So why are the guns coming back?

Many Americans have participated in a gun buy-back. They’re events held at police stations, churches, community centers and other locations, allowing people to turn in their weapons with the promise that they’ll be destroyed.

The buy-backs, often funded by charity, give people an incentive to get rid of guns that could result in accidents, suicides or crimes, and make sure they don’t end up back on the streets.
