What is the law on the right to order a suspect out of his car with his hands up?

The detectives had reason to believe Sanchez was armed and dangerous. The hotel manager informed the detectives the suspect had a gun, which he pointed at people in the hotel lobby. When the detectives located the taxi they believed contained the suspect, they were entitled to take reasonable steps to protect themselves by drawing their firearms and ordering Sanchez out of the car with his hands up. See United States v. Alvarez, 899 F.2d 833, 838-39 (9th Cir.1990) (investigative stop not an arrest where officers ordered suspect out of his car while brandishing their weapons when officers had strong reason to believe suspect was armed and threatened the officers' safety).
