John Wesley Hall notes a court opinion on FourthAmendment.com that some readers may wish to note — particularly if they are confessing to criminal conduct in their “private” communications:
There is no Fourth Amendment issue in a police officer posing as a false friend on social media accounts to see defendant’s private pages he shares with others. Here, defendant was seen wearing a gold chain taken from his robbery victim, and it was admissible in evidence. People v. Pride, 2019 Cal. App. LEXIS 34 (4th Dist. Jan. 11, 2019).
