Pace v. City of Des Moines, 201 F.3d 1050, 1054 (8th Cir. 2000) (“In this case, although it may be true that Officer Danner photographed Mr. Pace as quickly as possible, we believe that Officer Danner’s actions were too intrusive to be considered merely part of an investigative stop rather than a search fully implicating Mr. Pace’s fourth amendment rights. It is apparent to us that being ordered to go outside and to take off one’s shirt so that a police officer can take pictures involves much more fear and humiliation than simply being asked questions or being compelled to identify oneself. We believe that a reasonable officer cognizant of clearly established law would realize that such an imposition requires a warrant, something that Officer Danner did not obtain.”).
