Judge Sharon Johnson Coleman alluded to secret FBI recordings of Daoud made during the 2012 FBI sting that ensnared him. Coleman said Daoud was uniquely immature at the time, when he was 18, noting how Daoud is heard giggling almost constantly as he brainstorms attacks to avenge what he saw as the West’s war on Muslims.
It probably won't be popular to say, but this was mostly a political stunt by the FBI. They entrapped this "dumb as rocks" teenager. The 18 yoa had no association with any radical organizations. He had no bomb making skills. He had no bomb making materials. He thought he was getting a bomb from FBI agents that they soaked in diesel to make him believe it was real.
If this is what the FBI does to stop terrorists it's a miracle there haven't been more terrorist atrocities.
