District of Columbia Court of Appeals May 13, 2004, 00-CF-65, 00-CF-893 (Trice v. United States)

GLICKMAN, Associate Judge.

That police have legally sufficient grounds to stop a particular person who they suspect has committed a crime,

see Terry v.

Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968), is usually not a sufficient justification in itself for stopping the suspect’s companions or other bystanders too. But that usual rule tolerates exceptions for' exigent circumstances.
