How many criminals with active bench warrants or other issues with the police would come anywhere near such an event?

These gun buybacks are advertised as 'no questions asked' and nobody gets arrested on the spot.

The criminals use these events as a great way to dump dirty guns.

If they are really concerned, they send one of their girlfriends or relatives to do the dump for them.
