I apologize for the use of a news clip from Fox — the written article isn’t much better but they were the first to break the story.
Here’s the skinny: Jesus Duenas, a FOID card holder, purchases a handgun after the ban is lifted. He does not immediately obtain a Chicago Firearms Permit. In an unrelated incident, neighbors call police to complain about noise and the police use this opportunity to shake him down. They confiscate the handgun after entering the home without a warrant and charge him with having an unregistered firearm.
The judge dismisses the gun charge because the city of Chicago does not have a gun range and this is why Duenas was unable to comply with the ordinance.
Although the fact that there are CFP holders in Chicago this bit of information seems to be lost on the Fox news anchors. It’s at least good for a laugh.
In all seriousness I hope to get some more details on this case and hopefully from a better journalistic source.
