amnesties like this are pretty common tho, and unlike in serbia the government even pays people for bringing stuff in. nothing dangerous ever gets taken off the street, it's stuff like revolvers that were hiding in gma's attic, broken shotguns, antiques that were worth less than the buyback amount, etc. lately there have been jokers trying to bankrupt the amnesties by 3d printing tons of small guns and turning them in.
The number of guns collected is small, and criminals usually steer clear, officials say.
