That 'loophole' wasn't a really 'loophole' and anyway, no longer exists. It was 'closed' a few years ago.
It did pertain to a gun in a zippered pouch (fanny pack) with the magazine in a separate partition of the pouch. But the Cook County States Attorney, notorious gun grabber DICK DeVine, warned all that no one better try it as he'd prosecute anyone to the fullest extent of the law (more so than a gang banger). Then the IL General Assembly closed the 'loophole' with more exact language as to how a gun can legally be transported and Fanny Packs are now a specific no-no.
btw, The org that was pushing this 'carry loophole' was Concealed Carry, Inc. and is now out of business due to legal fees (he had a good idea but was fighting a losing battle).
A woman was prosecuted for carrying an unloaded handgun in her purse into a Courthouse somewhere downstate. The ILSC said that a purse qualified as a case and the woman was declared 'not guilty'.
The DuPage County Prosecutor publicly announced he would no longer prosecute any 'fanny pack' cases in his jursidiction.
