Summary

Defines key words used in criminal rules about blocking or lying to official investigations and proceedings. "Official proceeding" covers things like federal courts and judges, federal grand juries, Congress, federal agencies acting under the law, and insurance regulation that affects interstate commerce. "Physical force" means doing something physical to someone, including locking them up. "Misleading conduct" covers five basic ways to mislead: knowingly lying, leaving out or hiding important facts, offering false or forged writings or recordings, offering misleading samples or objects, or using tricks or schemes to deceive. A "law enforcement officer" is a federal worker or someone authorized to act for the federal government to prevent, investigate, or prosecute crimes, or a probation or pretrial officer. "Bodily injury" includes cuts, bruises, pain, illness, loss of function, or any other body harm, even if temporary. "Corruptly persuades" does not include conduct that would only be misleading if the person lacked the required intent. For the law about obstructing Congress (section 1505), "corruptly" means acting with a wrong purpose, including lying or hiding, changing, or destroying documents. The chapter does not punish honest, lawful legal representation given in or before an official proceeding.
