CHICAGO (WLS) — DNC or not, the Chicago Police Department is responsible for protecting residents, protesters, property, businesses and neighborhoods.

There will be some backup from police departments outside Chicago, including Milwaukee, where the Republican National Convention was being held. But police officials told the I-Team that there are not many out-of-town officers and that CPD is working 12-hour shifts covering the Democratic National Convention and regular operations in the community.

The U.S. Secret Service is responsible for securing the venues, delegates, party officials and candidates, employing hundreds of federal agents from special teams from other agencies, including the Bureau of Alcohol, Tobacco, Firearms and Explosives’ bomb-sniffing dog unit and explosives technicians on standby.

“We are bringing ten dogs to the DNC and their job at this event is to look for unattended luggage that someone may have left behind or a suspicious package,” said Kurt Bentley, Special Agent K-9 Handler for ATF-Chicago.

“Anyone entering the interior of the event will be searched by Department of Defense dogs,” said ATF-Chicago Special Agent K-9 Handler Dan Durkin.

“We have hand tools and all the other tools we need to take things apart or destroy something like that. We can investigate a crime scene. We can collect evidence,” said Anthony Zito, Special Agent Explosives at ATF-Chicago.

“The ability to set things off is constantly changing. So that’s becoming kind of an increasing threat. And we try to stay on top of that kind of technology,” said Stewart Graham, special agent for explosives at ATF Chicago.

When asked if Hollywood was good at portraying the way agents go about discovering an explosive device, John Richardson, Special Agent Bomb Technician at ATF-Chicago, said, “If you have to cut a wire, that’s a really bad day.”

In addition to regular police forces, 250 military police from the Illinois National Guard are on standby, according to Illinois Governor JB Pritzker.

“They’re really on standby, they’re on the edge. Nobody expects that we’ll have to use them for anything very serious. We also want to make sure that we have additional police personnel in uniform who are trained as police officers. We’re just trying to cover all eventualities and make sure we do everything right,” Pritzker said.

The last time the National Guard was activated was during the riots following the murder of George Floyd. They did what they would do if activated during the DNC: They managed street closures and traffic flows to relieve pressure on the Chicago police.
