Is a person's presence in a high-crime area sufficient to establish reasonable suspicion of criminal activity?

Although a person's presence in a high-crime area is not enough by itself to create a reasonable suspicion that he is involved in criminal activity, the "setting is a factor that can lend meaning to the person's behavior. [Citations.]" (People v. Limon (1993) 17 Cal.App.4th 524, 532.) "The time of night is another pertinent factor in assessing the validity of a detention." (Souza, supra, 9 Cal.4th at p. 241.) A suspect's "evasive conduct" and "sudden flight" from police also tend to establish the existence of reasonable suspicion. (Id. at p. 242.)
