Weird news - Hearing of a robbery before it could happen

It is the stuff of science fiction where one if able to figure out when a crime will happen in the future. In the current case, where a phone call arrives at emergency services, the dispatcher listens in, trying to figure out if somebody will say something, or maybe somebody is already in an emergency and is unable to communicate. And then suddenly the dispatcher hears abut a plot, with people discussing a robbery about to take place, but there are no details about the location where the robbery could happen, although the name of the police chief was discussed.
What was funny was that the police chief was in a restaurant while the police was trying to pinpoint the location of the callers, and after some amount of trying to determine the location, it was determined that the would-be criminals were highly intoxicated in a car in the parking lot, and so when they were caught, they were charged with being drunk in public rather than attempted robbery (link to article):

The mysterious phone call arrived about 9 p.m. Saturday night. A Danville, Kentucky, dispatcher answered, but the other end was silent. Instead of hanging up, the dispatcher continued to listen, fearing an emergency might be unfolding in the central Kentucky town of 16,000. Eventually, the dispatcher was able to make out tidbits of a conversation between two male voices. "They were saying things like, 'What if I went in there with a gun and what if we robbed the place?' " Danville Police Chief Tony Gray said. "Then the other one said something like, 'What if they know it's us? We go there all the time.' Gray said that both of the men were "highly intoxicated" and that one of them, though he didn't realize it at the time, was still on the phone with dispatch. The chief said he recognized one of the suspects from his high school class. "He had accidentally butt-dialed emergency dispatch after they started talking," Gray said. "The entire phone call from start to finish was about 14 minutes."
