Brady Campaign campaigning
Against the Ill. Firearm Owner ID card. They want background checks in addition to the firearm permit, because the permit spans ten years. (I think there is a requirement, for a gun permit system to exempt the holder from background checks, that the permits not go beyond a certain time, or have a way to revoke if the holder is convicted of something disabling).
UPDATE: see comments. Carl in Chicago, who oughta know, says the ID cards are updated if convictions occur, and background checks are run for each sale atop them. If that's so, then Brady is campaigning only because they don't understand the law.
