Dist.Ct. did not err in dismissing defendant's section 2255 habeas petition that challenged validity of his convictions under 18 USC section 924(c) for use of firearm during underlying crime of violence. Record showed that defendant had received seven concurrent life sentences for crimes related to deadly kidnapping scheme, as well as consecutive 45 year-imprisonment for his section 924(c) convictions. As such, instant denial was appropriate under harmless error grounds, since: (1) any error in his section 924(c) convictions would not have effected his seven life sentences for other crimes, which were not contested in instant habeas petition; (2) defendant had not established that he would suffer any concrete, non-speculative collateral consequences if Ct. of Appeals declined to reach merits of his habeas claim; and (3) defendant failed to show that there were any consequences affecting his "custody" for purposes of seeking habeas relief. (Dissent filed.)
