See, a federal court has ruled that Illinois must have some provision for legal carry of arms within their state. Other states have carry laws that basically boil down to "every honest citizen without a license" (constitutional carry), "any honest citizen who asks for a license" (shall-issue), and "you have to beg for permission, but sometimes we'll grant it." Illinois was the only state that didn't even let you beg for permission, and the court decided that didn't pass muster under the 2nd Amendment, so it struck down the law and gave the state 180 days to come up with something else.
In the 1950s, Democratic politicians in Virginia, led by Sen. Harry Byrd Sr., undertook an effort called "massive resistance." Through various legislative and administrative means, they sought to circumvent the mandate for school integration that the Supreme Court had issued in the 1954 case of Brown v. Board of Education.
Similar stirrings can be heard today in Illinois--specifically, from the Cook County State's Attorney's office, which prosecutes crimes in Chicago. At issue is not the 14th Amendment's guarantee of equal protection before the law, but the Second Amendment's guarantee of the right to keep and bear arms.
