Spouses suspecting an unfaithful partner have an unlikely ally: automatic toll-booth passes with detailed electronic records that divorce attorneys are using to prove infidelity. "It's an easy way to show who took the off-ramp to adultery," one lawyer quipped. The E-Z Pass devices, which are usually found on a driver’s dashboard, have also helped in criminal cases.
One woman was convicted of killing her husband after prosecutors retraced her steps using toll records. An AP survey found that seven of 12 states using the devices would provide records to authorities, despite objections from the ACLU.
