Using arcane secret formulas and mountains of statistical information, Dr. Garvin McCain, professor emeritus of psychology at UTA, predicts crime like the weatherman forecasts rain.
And while the weatherman may concede a margin of error, McCain is not afraid to tell anyone that his predictions--backed, he says, by 38 years of research experience--are 88.7 percent accurate.
Never mind that Dallas police say McCain's forecasts are meaningless. The 73-year-old professor insists that his figures are the crime-fighting breakthrough citizens and police are looking for.
Sure, it seems kind of strange to boil down an incredibly complex phenomenon--crime--into a simple daily forecast. But McCain's attitude is summed up in a Peanuts cartoon posted on his office bulletin board. The card shows Linus cuddling his security blanket, and reads: "No problem is so big or so complicated that it can't be run away from."
If people harken to his daily crime forecast, McCain says, one thing they can start dodging is crime.
On Friday, May 5, as meteorologists all across Dallas forecasted cloudy skies with a 60 percent chance of thunderstorms and highs in the 70s, Dr. McCain predicted 22 robberies, 35 aggravated assaults, 125 thefts, and a high of 55 burglaries.
At the end of the day, Dallas police recorded 18 robberies, 21 aggravated assaults, 156 thefts, and 38 burglaries--showing McCain way off for assaults and burglaries that particular day.
Rapes and murders, incidentally, do not register in McCain's crime forecast. "I'm happy to say there are not enough of them reported to make a very decent prediction from," he explains.
McCain says his years as a researcher have enabled him to glean certain insights into crime that figure into his forecasts, which he began issuing to media outlets in May of this year.
The professor has observed, for example, that the greatest number of violent crimes occurs on Saturday, and the greatest number of non-violent crimes occurs on Friday. He's also noticed that the fewest non-violent crimes, such as theft and burglary, occur on Sunday--perhaps "because more people are at home, so you don't go burglarizing when someone is there."
Whether these are words of wisdom or just common sense, McCain hopes to sell them to the news media. So far, he hasn't had any clients for his crime forecasts and hasn't decided what he would charge for his reports if he did. "I'm not into the business aspect of this thing," he says.
A few months ago, McCain established a private business, McCain Inc.--which seeks to become the crime weathervane for cities all over the country. To announce McCain Inc.'s arrival in Dallas, his test city, the professor faxed the first batch of his daily crime forecasts to several media outlets, including the Dallas Observer.
"You don't have a local television outlet that doesn't have a weather forecaster," McCain says. "I'm planning on doing the exact same kind of thing, except it will cost [TV stations] a lot less."
McCain's plans for his crime forecast service go far beyond local television, however. He envisions a day when police officers and academies will use his predictions to deploy officers in crime-prone areas, and train rookies on "what's going down on the street."
McCain can't say how his forecasts will aid the average citizen, except that "if people are conscious about what's going on I think we have a leg up."
Indeed, these words come from a man who knows the importance of accurate prediction. McCain was an Army pilot in World War II, and recalls a day when he soared off into the sky from a base in India after receiving a meteorologist's forecast of clear skies. Little did he know that a monsoon was in store for him.
McCain ran into the ferocious winds over India. "The radios just went crazy--the dials couldn't do a thing," he recalls.
McCain, who has never trusted a meteorological report since, says his crime crystal ball--based on a series of mathematical computations that took him four years to develop--gives a sharper picture.
"I'm the only one who knows what goes into it, I'm the only one who came up with it," he says. "I'm to blame."
McCain won't give away his formula, but does say it's based on factors such as the occurrence rate for each type of crime, and the time of the day and week. The time factors are most important, he says, because they "account for 75 percent of the variance" in crime figures. All of McCain's numbers are based on historical data gathered from police reports.
McCain ventured into crime prediction after years of conducting research on animal behavior, and later, the effects of prison crowding on inmate behavior. One time while finishing a book, he recalls experiencing a "real thirst for some data. I needed a data fix in the worst way." It was then that a colleague told him about some bizarre research that sought to prove a direct correlation between murder and temperature--the theory being that an increase in Fahrenheit contributes to a higher murder rate.
