Chicago buying guns off the street

The city of Chicago is hoping to take a record number of guns off the street this weekend.

On Saturday, the city will be in the gun business, as it will pay -- no questions asked -- $100 for every gun turned in to one of 25 participating churches.

Last year, using money from corporate donors, the city purchased a record 6,700 guns in a similar buyback program.

When people turn in guns they will receive a $100 prepaid MasterCard. They'll get $10 prepaid cards for BB guns, replica guns and air guns.
