United States v. Michael Weaver
808 F.3d 26
D.C. Cir.2015Background
- ATF agents investigated Michael Weaver for drug trafficking, obtained an arrest warrant in 2010, and located him in 2012 at a new apartment.
- Officers knocked, heard movement, announced “police” but did not state they had an arrest warrant or their purpose; they then used a key to unlock and immediately entered, subdued and arrested Weaver after a brief struggle.
- Upon entry an officer smelled and then observed marijuana; agents later obtained a search warrant and seized multiple kilograms of marijuana and other drugs and cash. Weaver was charged on additional counts based on that evidence.
- Weaver moved to suppress, arguing the entry violated the Fourth Amendment knock-and-announce rule and that the evidence discovered was the fruit of that violation; the district court denied suppression and Weaver appealed.
- The panel majority reversed: applying Hudson’s framework (causation and cost-benefit deterrence), it held Hudson’s search-warrant result did not control the arrest-warrant context and that exclusion was appropriate because the knock-and-announce violation caused officers to enter and see evidence they otherwise would not have.
Issues
| Issue | Weaver's Argument | Government's Argument | Held |
|---|---|---|---|
| Whether the exclusionary rule applies when officers violate knock-and-announce while executing an arrest warrant at the suspect’s home | Weaver: violation caused the discovery of evidence; suppression required | Gov: Hudson forecloses exclusion for any knock-and-announce violation | Held: Exclusionary rule applies in the arrest-warrant-at-home context; suppression required |
| Whether Hudson v. Michigan controls this situation | Weaver: Hudson limited to search-warrant context and is distinguishable | Gov/Dissent: Hudson bars exclusion for all knock-and-announce violations | Held: Hudson’s analysis governs the inquiry but is distinguishable on facts; arrest warrants materially differ from search warrants |
| Causation: was the knock-and-announce violation the but-for or proximate cause of obtaining the evidence? | Weaver: failure to give opportunity to surrender caused officers to enter and view evidence | Gov: even if violation occurred, evidence would have been discovered regardless | Held: Court found a strong causal link — unannounced entry led to interior intrusion and observation of drugs |
| Balancing deterrence benefits vs. societal costs of suppression | Weaver: deterrence valuable because officers have strong incentives to violate when only an arrest warrant exists | Gov: costs (letting guilty go free, litigation flood, officer safety) outweigh deterrence per Hudson | Held: In arrest-warrant context deterrence is appreciable and outweighs costs; exclusion justified |
