Following are key points from this Washington Post article:
A Muslim Washington D.C Metro Transit officer Nicholas Young was arrested for providing support to ISIS terrorists after being monitored by authorities for over seven years. The go-ahead to arrest Young was given when he sent mobile messaging cards to an undercover federal agent thinking they would be used by Islamic State fighters overseas to communicate.
During the seven years under surveillance Young has engaged in activities such as:
— He had given advice to suspected terrorists while on patrol and bragged about wishing to join ISIS
— He threatened FBI agents and also assisted jihadists
— He threatened to kidnap and torture an FBI agent and sink the head of anyone who crossed him to the bottom of a lake
— He threatened to bring guns into a federal courtroom
— He traveled to Libya twice in 2011 to fight against Moammar Gaddafi.
— He gave a person working with law enforcement advice on how to travel to Syria, including how to avoid undercover agents
— He dressed up as a “Jihadi John” at a 2014 Halloween party carrying around a headless orange jumpsuit filled with paper, and he dressed up as a Nazi and carried around Nazi memorabilia
— He collected a large number of firearms including an AK-47 RPG
