The officer had reasonable suspicion for a patdown based on a BOLO for defendant that he was armed and dangerous. Defendant wasn’t in custody when he was asked about where the gun was. United States v. Hogan, 2017 U.S. App. LEXIS 6118 (11th Cir. April 10, 2017).
Of course this is probable cause: “Defendant had sexually graphic conversations with a presumably fourteen-year-old girl, talked about having sexual contact with her (and other minor girls), and sought to coerce or entice her for sex. Moreover, Defendant indisputably sent a picture of his penis to the presumably fourteen-year-old girl. The affidavit established the necessary nexus between the conversation and image and Justin Walling, and the affidavit established Walling’s devices at his residence as the origin of those conversations.” United States v. Walling, 2017 U.S. Dist. LEXIS 54250 (W.D. Mich. April 10, 2017).*
