Whether Section 924(c) criminalizes two separate offenses - 'carry or use' and 'possession in furtherance of' - and whether both elements must be explicitly charged in the indictment

QUESTIONS PRESENTED IS THERE AN ACKNOWLEDGED CONFLICT AMONG THE SISTER CIRCUITS AS TO WHETHER SECTION 924(c) GRIMINALIZES TWO SEPARATE OFFENSES (1) "CARRY OR USE" A FIREARM DURING AND RELATION TO A DRUG TRAFFICKING OR CRIME OF VIOLENCE AND (2) POSSESSING A FIREARM "IN FURTHERANCE OF" SUCH A CRIME: AND WHETHER BOTH ELEMENTS MUST BE EXPLICITLY CHARGED BY THE GRAND JURY TO SERVE PROTECTION OF THE FIFTH AMENDMENT; AVOIDING POST-GRAND JURY DECISIONS AND CROSS-MATCHING “POSSESSION” WITH "USE" OF THE GUN?
