What rights does a police officer have to verify or dispel suspicion?

The right to verify or dispel suspicion is meaningless unless officers may, when necessary, forcibly detain a suspect. "The Fourth Amendment does not require a policeman who lacks the precise level of information necessary for probable cause to arrest to simply shrug his shoulders and allow a crime to occur or a criminal to escape. On the contrary, ... [a] brief stop of a [231 Cal.App.3d 13] suspicious individual, in order to determine his identity or to maintain the status quo momentarily while obtaining more information, may be most reasonable in light of the facts known to the officer at the time." (Adams v. Williams (1972) 407 U.S. 143, 145-146, 92 S.Ct. 1921, 1923, 32 L.Ed.2d 612, emphasis added.) With reasonable suspicion, "the officer is entitled to make a forcible stop" and, if he has reason to believe the suspect is armed and dangerous, conduct a limited search for weapons. (Id., at p. 146, 92 S.Ct. at p. 1923, emphasis added, fn. omitted.)
