However, unlike some others in this thread, I don't find myself privately rejoicing that a legal technicality has now presented him with a chance of freedom. Whatever the causes of his antipathy toward the United States, and however you feel about the surveillance state and general disregard among law enforcement for our constitutional rights, Mohamud demonstrated a very clear intention to kill many people whom he never met. This cannot be attributed to entrapment, even if it is ultimately shown that his constitutional rights have been violated.
I hope Mohamud has overcome whatever psychological state led him into this situation. If it could be shown that he is truly better, I would have no objection to his return to society. But there is something absurd about the possibility that a person with a demonstrated propensity for mass violence might be returned to society at large without any legal restrictions, psychological treatment, or period of supervision.
