The Courthouse - Revisited

In 2019, two penetration testers named Justin Wynne and Gary (now Gabby) DeMercieo were hired by the Iowa Judicial Branch to test the security of several courthouses across the state. They had a 28-page contract, a "get out of jail free card" with the names and phone numbers of three state officials who had signed off on the work, and years of experience doing exactly this kind of physical security assessment. They broke into the Dallas County Courthouse in Adel, Iowa, at midnight, tripped the alarm, waited for police to arrive, showed their paperwork, and expected to be sent on their way. Instead, the sheriff ordered them arrested for burglary—a felony carrying up to seven years in prison. What followed was a six-year legal battle that would test whether the profession of physical penetration testing could survive contact with the criminal justice system.
