What is the test for showing reasonable suspicion of sexual assault?

We therefore conclude that the encounter was consensual, and as such, no showing of reasonable suspicion was required. "[L]aw enforcement officers do not violate the Fourth Amendment by merely approaching an individual on the street or in another public place, by asking him if he is willing to answer some questions, by putting questions to him if the person is willing to listen, or by offering in evidence in a criminal prosecution his voluntary answers to such questions." (Florida v. Royer (1983) 460 U.S. 491, 497 [75 L.Ed.2d 229, 236].)
