What is the test for reasonable suspicion in criminal proceedings?

Reasonable suspicion requires that "the detaining officer can point to specific articulable facts that, considered in light of the totality of the circumstances, provide some objective manifestation that the person detained may be involved in criminal activity." (People v. Souza (1994) 9 Cal.4th 224, 231.) The reasonable suspicion standard "is not a particularly demanding one, but is, instead, 'considerably less than proof of wrongdoing by a preponderance of the evidence.' " (People v. Letner and Tobin (2010) 50 Cal.4th 99, 146.)
