Justin Prinstin was a scout for the Los Angeles Angels, an American professional baseball team, and had previously worked as a scout for the KBO LG Twins. He was recently fired after being caught filming Colorado Rockies coaches with his cell phone. While MLB allows scouts to film games, using electronic devices to steal signs is prohibited. Prinstin had previously criticized sign-stealing scandals and labeled the use of technology to steal signs as "spy activity." This incident led Prinstin to take actions contrary to his own claims, ultimately forcing him to retire from baseball.
