in 2010 the fbi spent the better part of a year convincing a young somali refugee named mohamed mohamud to attempt to set off a fake bomb at a christmas tree gathering in portland, including having him detonate a real bomb they provided him as a “trial run”. he’s now serving 30 years in federal prison. after the operation became public, the mosque where he attended services suffered a real arson attack for which the perpetrator was sentenced to five years. https://en.m.wikipedia.org/wiki/2010_Portland_car_bomb_plot
