Here's a short sample and part of the bigger story you can read here, at Root River Siren:
Critics of gun buy-backs (who can't comprehend the notion of anyone voluntarily surrendering a firearm) say the gun buy-backs only net junk guns, BB guns and air rifles.
These aspersions are cast to dampen community support (i.e. donations) for the event.
To make sure they are correct, members of Wisconsin Carry, Inc. came to Racine last Saturday weighted down with BB guns and broken guns to sell and promptly released a statement saying the guns purchased in the buy-back were worthless.
