A new Cook County Sheriff's team is crisscrossing the suburbs to seize guns from thousands of people whose Firearm Owners' Identification Cards have been revoked. More than 3,000 people in Cook County have failed to surrender their revoked FOID cards to the state. Sheriff Tom Dart said he thinks many of them continue to possess firearms.Mind you, "revoked" probably means they committed a crime (or had a restraining order taken out against them) that makes them ineligible to own the firearms under state law, federal law, or both. But it still points out that if the government decides you shouldn't have firearms, having a list of gun owners makes taking those firearms back a lot easier. Whether the reason for taking them back is individualized and legitimate... or not.
Hat tip to saysuncle, who really shouldn't have said "expired" when his source said "revoked".
