  • Chicago adds undercover police for the Bank of America Chicago Marathon

The city has decided to increase security for the Bank of America Chicago Marathon Sunday, placing more undercover police officers in the crowd. The changes were made in response to the Las Vegas mass shooting that left 58 dead. “It’s going to be an open event, as it always is,” Anthony Riccio, the chief of the Chicago Police Department’s Organized Crime Bureau, told reporters Thursday. “That said, we learn from every event, every tragedy we learn from, and we learned from Vegas as well. So one of the things we’re doing is we’re putting a significantly larger number of undercover officers. They’re going to be intermingled with the crowd, they’re going to be around the runners. They’re going to be at the finish line. They’re going to be at the start line. So we’re going to have a significant amount of undercover officers that are going to be blending in there to keep an eye on things as well.” Security will “double-check and triple-check” the plans until the race starts, Mayor Rahm Emanuel said.
