Ironically, Chicago, Illinois, with famously strict gun laws, including a (prior) ban on private possession of handguns, served as the basis for SCOTUS’ 2010 decision in McDonald v. City of Chicago that Second Amendment applies to the states through the Fourteenth Amendment.

On July 9, 2013 Illinois became the last state in the country to allow citizens of the state the right to carry concealed weapons.  Possession of the permit is granted to those who are 21 or older and who pass a 16-hour training course.  Applicants may be denied a permit if the law enforcement agency finds reasonable suspicion that the applicant is a danger to themselves or others.

Illinois has water boundaries with other states, in some cases further complicating an interstate transportation and/or reciprocal carry analysis. To the north, Illinois borders Wisconsin, although the boundary line lies in Lake Michigan.  Illinois’ eastern border with Indiana is within Lake Michigan and the Wabash and Ohio Rivers. The Ohio River is the southern border with Kentucky. The western border with Missouri and Iowa is the Mississippi River.
