“Section 213 in the Patriot Act [signed into law on October 26, 2001] also amends the Federal Rules of Criminal Procedure to allow authorities to search and seize the property of a target without notifying the owner. So-called sneak and peek searches are barred by traditional warrants. But these searches now can be conducted if the government argues that notification would engender an ambiguously stated ‘adverse result.’ ”
