A Washington D.C. metro transit officer has become the first U.S. law enforcement officer charged with giving financial support to ISIS.

NBC News reports that Nicholas Young, 36, was arrested at the transit agency's headquarters without incident and will appear in court on Wednesday. With the help of an undercover informant, Young was caught buying 22 gift cards for mobile messaging apps to aid the Islamic terror group overseas. He faces a 20-year prison sentence. 

The report adds:

He posed no credible threat to the Metro system, said Joshua Stueve, spokesman for the U.S. Attorney's office in Virginia's Eastern District. He was focused on aiding ISIS overseas, court documents say — not on an attack at home.

But this isn't the first time Young has been under surveillance. That started back in 2009, when he was reported to the FBI for suspicious behavior. Since then, he's been under near-constant surveillance, according to the report. "Which is why they were confident he couldn't use his job to pose a threat," it notes.

Court records on Young indicate he had "Nazi sympathies" and supported Islamic extremists. He told the FBI that he had traveled to Libya in 2011 to help the rebels take down Moammar Gadhafi. He even posed as an ISIS fighter 20 times with an FBI source and gave that source advice on how to avoid detection from cops.

Young was also found to be acquaintances with two D.C. residents who were convicted in terrorism cases, one who was convicted of supporting al Qaeda and another who pleaded guilty to planning a suicide bomb at the Capitol.

Even the NBC News report found it troubling that Young has been under the watchful eye of federal authorities for at least seven years and could only now be brought up on charges. It imagined that had Young become violent, the FBI "would have come under hard questioning about all their interactions with him for years — including surveillance and multiple FBI interviews."

This should be concerning to everyone.
