What is the current state of the law on investigatory stops where facts known to the police make apparently innocuous behavior suspicious?

This circuit has upheld investigatory stops where facts known to the police make apparently innocuous behavior suspicious to the police. In United States v. Bautista, 684 F.2d 1286 (9th Cir.1982), a police broadcast went out moments after a bank robbery describing the robbers and reporting the discovery of their getaway car on a certain side street. Two police officers concluded that the suspects might flee by proceeding to a through street leading out of the area, and proceeded to that street. A few minutes after the first transmission, they saw two men meeting the description about three blocks from the getaway car. Though it had been raining, the men appeared dry. Id. at 1287.
