I find it interesting that one of the proponents admits that its not actually about or likely to generate substantial revenue but is a form of violence reduction. One would think they would stick to the revenue opportunity song and dance.
I would be interested to see the report that states 1/3 of guns recovered on the streets came from suburban gun shops. I wonder if that is guns used by and possessed by criminals, or includes guns possessed by criminals that were recently stolen and recovered. Either way I find the initial statement to be misleading as the suburbs are the closest place for legal Chicago firearm owners to purchase or receive firearms.
When I lived in Chicago I usually stocked up on ammo at Cabela's in IN, since it was much cheaper than buying ammo at the range even including the gas to get there.
