You're asking me a question that's starting to get a little bit outside my area of expertise. I can tell you there are no false alerts. There are alerts that are more interesting than other alerts, for example, an alert where an offender has gone into a victim's exclusion zone. There might be an alert that is a “bracelet gone” alert, where an offender stepped away from his bracelet for a minute and then returned, and that alert clears up.
