The study was conducted by a gentleman by the name of Bill Bales. I have access to a copy of that study and would be happy to send it, Mr. Chairman, to the committee, if you desire.
The study looked at 2,700 offenders in Florida who were being tracked by GPS, and there were about 1,000 offenders being tracked by RF, and then there was a population of offenders who were not being tracked with any electronic monitoring at all. The data that was made available was several years' worth of data—I'm sorry I don't remember how many years it was—which Dr. Bales went through to come up with his results.
