On page 8 they say:
"We agree that the ordinances impose a burden on the exercise of a fundamental
right protected by the second amendment. At its core, the second amendment
protects the right of law-abiding citizens to keep and bear arms for self-defense in
the home. District of Columbia v. Heller, 554 U.S. 570, 635 (2008). In McDonald
v. City of Chicago, 561 U.S. 742, 778 (2010), the United States Supreme Court
stated that “it is clear that the Framers and ratifiers of the Fourteenth Amendment
counted the right to keep and bear arms among those fundamental rights necessary
to our system of ordered liberty.” See also Johnson v. Department of State Police,
2020 IL 124213, ¶ 37 (“the second amendment right recognized in Heller is a
personal liberty guaranteed by the United States Constitution and the fourteenth
amendment” (citing McDonald, 561 U.S. at 791)) "
I hope that's short enough quote to be "fair use".
