Is the failure to disclose exculpatory subpoena returns until post-trial a Brady violation warranting conviction vacatur; does the 'in concert' element of 21 U.S.C. 2252A(g) require aggregate or individual predicate offenses; where outside access to a user profile exists, is evidence sufficient to convict

I. Is The Failure to Disclose Subpoena Returns that are Exculpatory and Directly Related to a Defense Theory Until Post-Trial and Only Upon Request a Violation of Brady¸ And Should the Remedy for the Violation be to Vacate the Conviction? II. Should the “In Concert” Element of 21 U.S.C. 2252A(g) be Met by the Aggregate of Predicate Offenses or Does the Statute Require that Each Predicate Offense be Committed in Concert with At Least Three Others? III. Where There is Evidence of Outside Access to a Defendant’s User Profile on an Exploitative Site, Is Evidence Sufficient to Convict, Especially Where the Offense Requires a Specific Number of Predicate Offenses Committed in Concert with Others
