Thank you. That's a very good question.
One thing we learned from the pilot was the limitations on the equipment. Learning that allowed us to modify our procedures, our policies, and our protocols. We also learned from it that although there is a drift factor, there is sometimes, even taking that into account, good reason to engage an offender in questions as to why they were getting close to an area for which they may have had conditions requiring them to stay away.
To give you an example, sex offenders out in the community often have conditions that restrict them from places where young children meet, such as playgrounds, swimming pools, or schoolyards. Even though there may be some drift, if they're getting close to those zones and the drift is showing that they're in the zone, whether or not the drift was accurate we still have questions as to why they were coming close to an area such as that. It allows the parole officer to engage the offender in the kinds of discussions that are needed to supervise some of the conditions that are placed on offenders.
