Monitored for months DISP probationers are usually placed under electronic monitoring for three to seven months and can only leave the house to work and during other times authorized by their probation officer. A monitoring device installed in their homes receives a signal from the ankle bracelet and will contact police should the bracelet leave the device's range outside of the allowed times. At least once a day, the breathalyzer device known as the Sobrietor on a scheduled or random basis will emit an alarm directing the DISP participant to breath into the device. A voice verification system makes sure it's the probationer. If the Sobrietor detects any alcohol including any from shaving cream and mouthwash, it will inform police.
Any violations can result in short jail terms lasting only a few days.
Offenders are required to report any drinking relapses. Judge Baker often will sentence those who drink to five days in jail and those she believes are lying when they deny drinking despite the evidence are often sentenced to 30 days. She will force offenders to take polygraph tests if necessary. Repeat offenses will lead to revocation of probation and a return to jail. Montes said he typically sees three to five violations a day.
