Failure to leave a copy of the search warrant does not require suppression. There is no prejudice. United States v. Robinson, 2019 U.S. Dist. LEXIS 99902 (E.D. Mich. June 14, 2019).
The CI was creditable because of admissions against interest and corroboration. The protective sweep prior to the warrant arriving was reasonable and resulted in no seizure. People v. Elder, 2019 NY Slip Op 04784, 2019 N.Y. App. Div. LEXIS 4775 (3d Dept. June 13, 2019).*
