As mayor of north suburban Highland Park, Nancy Rotering has been in the thick of the debate over gun control in recent years.
Since 2013, her suburb has prohibited weapons like the semiautomatic rifle used to kill 17 Parkland, Florida, high school students and teachers on Valentine’s Day. The Illinois city’s gun ban has survived a court challenge, with the U.S. Supreme Court in 2015 refusing to hear an appeal of a ruling that upheld the Highland Park law. The practical effect of that decision was to signal other local governments that they could legally impose bans on certain types of military-style guns without violating the Second Amendment.
