Duffell v. United States

How later courts describe this case

• sustaining a conviction without proof of defendant’s knowledge of the law because “the word ‘knowingly modifies the verb ‘to deliver,’ which it immediately precedes.”
• rejecting defendant’s contention that 18 U.S.C. § 922(e) is unconstitutionally vague
• section 922 violated where defendant checked baggage subsequently determined to contain firearms; defendant arrested as he entered jetway to aircraft
• crime of knowingly shipping firearms without declaring them is not specific intent crime
• use of the word “knowingly” in federal firearms laws does not require specific intent
