>Ducks need to be in a row to bring someone like that to justice. NSA "has all of the information", but it was all obtained illegally so can not be used in a court of law. Legal evidence gathering takes time.
Military Tribunals have different rules regarding evidence,
" Evidence, including previous trial testimony and written statements, will be admissible if it tends to prove or disprove the case at hand. The exclusionary rule, which keeps illegally seized evidence out of a civilian criminal trial, does not apply."
