FL4: Collective knowledge doctrine with anonymous or confidential sources requires passing details on to fellow officer

When the collective knowledge rule applies to information from an anonymous or confidential source, the officer using the information has to have actual knowledge of the factors supporting its reliability. Zarcadoolas v. Tony, 2023 Fla. App. LEXIS 26 n.3 (Fla. 4th DCA Jan. 4, 2023). [Otherwise, truly weak information is sanitized by adding a step of hearsay.]

Defendant consented to entry of his home to obtain two cell phones. United States v. Barr, 2023 U.S. App. LEXIS 32 (11th Cir. Jan. 3, 2023).*

Pre-Carpenter obtaining of CSLI was in good faith. Siri-Reynoso v. United States, 2023 U.S. Dist. LEXIS 663 (S.D.N.Y. Jan. 3, 2023).*

A defense attorney is not ineffective for not filing a motion to suppress that would not win. Harmon v. State, 2023 Alas. App. LEXIS 1 (Jan. 4, 2023).
