917 F.3d 1055
8th Cir.2019Background
- In December 2014 Microsoft flagged seven images of child pornography uploaded from the email wadith@hotmail.com to SkyDrive; NCMEC notified Nebraska authorities.
- Detective Bryan Svajgl investigated, obtained a valid search warrant for Wadith Nader’s residence, and executed the search on March 17, 2015.
- A forensic scan of one of Nader’s computers produced numerous pornographic images, 23 keyword hits related to child pornography, and one hash value “of interest” (indicating a potential match to a known illegal image); the image for that hash was not reviewed onsite.
- Nader acknowledged uploading files to SkyDrive and said he might have accidentally uploaded child pornography; detectives seized computers and phones.
- Based on the SkyDrive uploads tied to Nader’s email, the forensic hits, and Nader’s statements, Svajgl consulted the on-call deputy county attorney, who agreed there was probable cause; Nader was arrested and charged with possession of child pornography.
- Nader sued under 42 U.S.C. § 1983 for unlawful arrest; the district court granted summary judgment for defendants on qualified immunity and municipal-liability grounds; the Eighth Circuit affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether officers had probable cause for a warrantless arrest | Nader: officers lacked probable cause because minimal further investigation (examining the hashed image) would have shown it was not child pornography | Officers: totality of circumstances (SkyDrive uploads from Nader’s email, forensic keyword hits, Nader’s admission) provided probable or at least arguable probable cause | Court: Officers had probable cause/arguable probable cause; arrest lawful and qualified immunity applies |
| Whether officers were required to perform additional on-scene forensic review before arrest | Nader: failure to review the image was a lack of minimal investigation that would have exonerated him | Defendants: no duty to conduct a "mini-trial"; further on-scene review not required when circumstances already support probable cause | Court: No further minimal investigation was required here; arrest proper |
| Whether remaining individual defendants share liability | Nader: other officials and prosecutors contributed to unlawful arrest | Defendants: same facts negate any constitutional violation; qualified immunity for individuals | Court: All individual defendants entitled to qualified immunity |
| Municipal liability for Sarpy County and City of Papillion | Nader: municipality liable for constitutional violation by its employees | Defendants: no underlying constitutional violation by employees, so no municipal liability | Court: No municipal liability because no unconstitutional act by a municipal employee |
