CA10: QI properly granted in homeowner’s 4A claim against officer executing arrest warrant for another

The district court properly granted qualified immunity to a trailer resident’s Fourth Amendment claims against a deputy sheriff stemming from a search and seizure conducted while executing an arrest warrant for a guest staying in the trailer. The law was not clearly established that entering the trailer under such circumstances violated the resident’s Fourth Amendment rights. The officer’s order requiring the resident to exit his bedroom was not clearly unlawful because there were circumstances under which law enforcement personnel were permitted to temporarily detain third parties in the course of executing a valid arrest warrant. The officer could have reasonably believed that his use of a police dog was permissible after he loudly announced that he would deploy the dog if the occupant of the bedroom did not emerge. Crall v. Wilson, 2019 U.S. App. LEXIS 11420 (10th Cir. Apr. 19, 2019).*
