[Ed. – Doesn’t seem surprising.]
More than 75 percent of the people who received gun license revocations last year in Illinois ignored the notices, Illinois State Police said.
State police issued a report late Thursday in response to questions about the gunman who fatally shot five co-workers at a suburban Chicago warehouse last week. The man, Gary Martin, used a gun in the Aurora attack that he never should have been allowed to have because his firearm-owners card was revoked in 2014. …
State police say their records show that about 10,800 firearm-owner cards were revoked in 2018 but that only about 2,600 of those individuals returned notices. Revoked card holders are supposed to return the notices, or firearm disposition records, which document individuals receiving transferred firearms from revoked cardholders.
