Supreme Court of the United States, Pugin v. Garland (2023)
“ Individuals can obstruct the process of justice even when an investigation or proceeding is not pending. For example, a murderer may threaten to kill a witness if the witness reports information to the police. Such an act is no less obstructive merely because the government has yet to catch on and begin an investigation. As the Solicitor General persuasively states, one can obstruct the wheels of justice even before the wheels have begun to move; indeed, obstruction of justice is often “most effective” when it prevents “an investigation or proceeding from commencing in the first place.” ”
