I se I have not made my point clear here. The quoted statement is not referring to these defendants in particular, it is referring to those who try to use virtual currencies for criminal purposes in general - yet the language appropriate for referring to specific defendants creeps in here, presumably out of concern that some people cannot tell the difference.
When a crime has been committed, it was not allegedly done by a person or persons unknown, it was actually done by whoever they were. One of the jobs of the justice department is to catch criminals, not alleged criminals.
