Parker v. United States

How later courts describe this case

• "We reject [the appellant's] argument that any requirement that he acknowledge personal responsibility in order to gain the benefit of the two-level reduction impermissibly prejudices his right to appeal his conviction."
• justification jury instruction unwarranted because the defendant, who took the gun from a threatening third party, failed to show that he did not maintain possession any longer than absolutely necessary
• keystone of justification defense to a charge of being a felon in possession is that a defendant must have no alternative, either before or during the event, to avoid violating the law
