CA7: Drug dog’s 59% success rate still PC

The fact the drug dog here had only a 59% (or 80%) success rate is still probable cause. The fact a dog can’t tell the difference between legal and illegal cannabis is of no moment. It’s still probable cause. United States v. Plancarte, 2024 U.S. App. LEXIS 15766 (7th Cir. June 28, 2024). [Still, dogs can alert to residual odors, and that’s not a false alert. Success rate is different?]

The uncorroborated information from the unidentified citizen informant here was not reasonable suspicion on the totality. “[D]efendant was seized once he complied with Officer Leach’s order to raise his hands because, in that moment, his liberty was sufficiently curtailed to implicate his Fourth Amendment rights.” State v. Pires, 2024 R.I. LEXIS 56 (June 26, 2024).

The emergency aid exception applied to an officer pulling behind defendant’s car parked on a freeway on-ramp with the driver’s door open and the driver vomiting. The fact the officer did no more than inquire wasn’t of any moment. Commonwealth v. Ward, 2024 PA Super 133, 2024 Pa. Super. LEXIS 260 (June 28, 2024).*
