To prove any criminal charge, the evidence must be sufficient for a jury or judge as the case to make that conclusion beyond a reasonable doubt. For sample manner of proving that, see my last post above to Danny. There is no right to be a member of a violent organisation like AQ whatsoever within the right of association, which is intended for peaceful and reasonable conduct. There is no right to be a criminal conspirator in ordinary or serious crime, e.g., a group of burglars or insider traders, or a violent street gang, etc. As for a capital offence, IMO that can be applied in the case of criminal conspiracies sanctioning and conducting premeditated murder(s), of which AQ is most certainly engaged.
