You can listen to the police and some EMS if you go digital. I've got a Uniden 396 and a Realistic PRO-2096 and I get all kinds of PD and some EMS departments, especially the Rapid Transit police and helicopter life flights going in and out of University Circle. I don't get any ground level EMS comms or local fire departments but sometimes a distant one will pop up on a MARCS talkgroup.
Even if you're not in possession of a digital receiver try searching the repeater frequencies and you'll usually find some public safety voice transmissions there.
