"Reasonable man" is going to mean whatever the particular court wants it to mean in that particular case.
You're walking your dog down the road one night and a police car pulls across your path. The officer shines a spotlight at you and then stepping from his car calls out in a loud and authoritative voice, "You there, come here I want to talk to you! You got any knives, guns, or needles that are going to hurt me? Why don't you just 'assume the position' across the hood of my car? Like right now, boy."
You obey because you think you've been detained.
But were you?
Chief Justice Warren for the Court ([
Terry v Ohio) wrote that the Fourth Amendment was applicable to the situation, applicable ''whenever a police officer accosts an individual and restrains his freedom to walk away. So the court may well ask if a 'reasonable person' would think he was restrained. Recent court cases would say no; you weren't detained, you had a voluntary encounter with Officer Friendly. How does a 'reasonable person' know this? Well, according to the court, he knows because
- the officer didn't have a drawn gun
- there was only one officer
- he could turn around and have an avenue to leave the encounter
- there were no flashing emergency lights
- the officer had issued no commands, only expressed desires and requests
- the officer never touched the person
How else might a 'reasonable person' know his encounter was voluntary?
Asking for identification, by itself, is not a detention. (People v. Ross (1990) 217 Cal.App.3rd 879; People v. Lopez (1989) 212 Cal.App.3rd 289.)
But; retaining the identification longer than necessary is a detention, and illegal unless supported by a reasonable suspicion the detainee is engaged in criminal conduct. (United States v. Chan-Jimenez (9th Cir. 1997) 125 F.3rd 1324:
Asking a person to
remove his hands from his pockets (done for officers' safety), without exhibiting a "show of authority such that (a person) reasonably might believe he had to comply," is not, necessarily, a detention. (People v. Franklin (1987) 192 Cal.App.3rd 935, 941; In re Frank V. (1991) 233 Cal.App.3rd 1232.)
Inquiring into the contents of a subject's pockets (People v. Epperson (1986) 187 Cal.App.3rd 118, 120.), or asking if the person would submit to a search (People v. Profit (1986) 183 Cal.App.3rd 849, 857, 879-880; Florida v. Bostick (1991) 501 U.S. 429 [115 L.Ed.2nd 389].), does not necessarily constitute a detention, so long as done in a manner that a reasonable person would have understood that he is under no obligation to comply.
Displaying a badge, or even being armed, absent active brandishing of the weapon, will not, by itself, convert a consensual encounter into a detention. (United States v. Drayton (2002) 536 U.S. 194 [153 L.Ed.2nd 242].)
Of late, the courts are doing everything in their power to characterize as 'voluntary' as much of any encounter with law enforcement as they can convince themselves is so. Police officers are being educated in the same manner, to not characterize or admit that an encounter is anything other than voluntary on the part of the citizen as only when officially detained do a citizens' rights protect his conduct.
