Good afternoon, Chicago.

After Naperville police allegedly found a 14-year-old carrying a loaded, semiautomatic pistol at a downtown “teen takeover” event last weekend, authorities are urging safety and, again, stressed they have zero tolerance for illicit behavior.

“While we encourage everyone to exercise their first amendment right and we encourage everyone to enjoy what the downtown provides, we need everyone to do that lawfully,” Naperville police Cmdr. Rick Krakow said. “There’s going to be zero tolerance for any sort of criminal behavior, from trespassing to disorderly conduct to fighting.”

Since May 1, there have been seven planned teen takeover events in Naperville, each with varying degrees of participation, Krakow said.

The latest, held Saturday, resulted in five arrests, including that of the 14-year-old, who was charged with one count of unlawful possession of a weapon, authorities said. Charges in other arrests included disorderly conduct and battery.

MJ Lenderman at Salt Shed: Perfecting the art of malaise

Watching MJ Lenderman at the Salt Shed yesterday was to be reminded of the curious power of exhaustion. It’s a beautiful, humid, rickety sound. You can hear in it why the sighs of Neil Young became inextricable from Watergate-era malaise, and how Lenderman, 50 years later, sounds like both a throwback to strung-out singer-songwriters of the ‘70s and very much of his own time.
