If you are the type of person who thinks shining a laser into a police helicopter at four in the morning sounds like a good time, be warned that the FBI can and will identify you by the cut and color of your underwear.

We know this thanks to a 23-year-old Texan named Kenneth Santodomingo, who according to the FBI was in the backyard of his Dallas home at 4:08am on January 28, 2013, shining a laser pointer into the cockpit of a Dallas Police Department helicopter called "Air 1." Santodomingo allegedly scored four direct hits on the cockpit; according to the FBI agent investigating the case, "the intensity of the light obscured the vision of the pilot and impaired the pilot's ability to control the aircraft."

The officers in the helicopter then used an infrared camera to track down the source of the light, and they directed police officers on the ground to a home on Lake June Road. When officers knocked on the door, Santodomingo opened it—but couldn't manage to unlock the burglar bars covering the door. He was, the FBI notes, "only wearing dark blue short style underwear." The officers had a conversation through the bars with their underwear-wearing subject, who at first denied any knowledge of what they were talking about. When the officers pointed out that the helicopter had recorded video of the incident, Santodomingo allegedly admitted that he had used a green laser to illuminate the helicopter. Why had he done it? Because he "wanted to see how far [the laser] would go."

In addition to this knowledge, Santodomingo will also learn just how far the judicial system will go in prosecuting such offenses. Previous experience tells us the answer is "all the way." He has been arrested and now faces federal charges. In preparing those charges, the FBI reviewed the footage taken by the police officers in the helicopter. As Special Agent Mark Sedwick put it in a court filing, "The video taken by the DPD helicopter showed that the individual using the laser in the backyard fit the description of Santodomingo and appeared to be wearing the same short style underwear at the time of the offense that Santodomingo was wearing when talking to officers."

Santodomingo faces a maximum of five years in prison and a $250,000 fine.
