Where does an accused killer go to say I am not a killer?

To a criminal court, to establish one's guilt or innocence. But you only go before a tribunal if you aided or assisted in the attacks on 9/11 - not so with regular criminal courts, which are established in order to determine the factual basis of the allegations made against you. The only way to be put in front of a tribunal is by being, in fact, guilty - a priori.
