The Fourth Amendment prohibits police from searching a person or their premises, or from seizing their property, without a warrant issued by a court upon a showing of probable cause. The War on Drugs, which began in the 1970s, considerably expanded law enforcement’s powers, and laws passed in the last 15 years as part of the “War on Terror” expanded them even further. Now, tactics that were originally authorized for counter-terrorist activities are primarily used in drug enforcement operations. A bill passed by Congress in 2001 authorized Delayed Notification Search Warrants (DNSWs), also known as “sneak and peek” warrants. Civil rights advocates charge that DNSWs allow law enforcement to engage in what are essentially legalized burglaries of private residences, raising serious Fourth Amendment concerns.
When executing a search warrant, officers must normally follow the “knock-and-announce” rule, meaning they must identify themselves as police and state their purpose before forcibly entering a residence. After executing a warrant, officers must provide the owner of any seized property with a copy of the warrant and a receipt for the property. Fed. R. Crim. P. 41(f)(1)(C). A court may issue a “no-knock” warrant when officers allege exigent circumstances that risk the destruction of evidence. This type of warrant sometimes results in a show of overwhelming force by police, but some courts have begun to restrict this practice on constitutional grounds.
In October 2001, Congress passed the USA PATRIOT Act. The law’s stated purpose was to “provid[e] appropriate tools required to intercept and obstruct terrorism”—giving it the title “PATRIOT” as an acronym. It established procedures for the issuance of DNSWs, which allow the delay of any required notice to the owner of the premises to be searched for “a reasonable period” after the execution of the warrant. Pub. L. 107-56 § 213 (Oct. 26, 2001), 115 Stat. 286; 18 U.S.C. § 3103a(b). A DSNW should “prohibit the seizure of any tangible property…except where the court finds reasonable necessity for the seizure.” Id.
