Which of the following is NOT a factor in determining reasonable suspicion?

The correct answer is that the subject's race is not a factor in determining reasonable suspicion. Reasonable suspicion must be based on specific and articulable facts that pertain to the situation at hand, rather than on characteristics like race or ethnicity. Law enforcement officers are guided by constitutional principles, specifically the equal protection clause, which prohibits racial profiling and ensures that decisions are made based on behavior and evidence rather than the physical characteristics of individuals.

Tips from known informants, recent crime patterns, and behavior suggesting possible criminal activity are all legitimate components that can contribute to an officer's reasonable suspicion. These elements provide a factual basis for suspicion that is necessary for further investigative action, such as stops or brief detentions. Thus, while the other options directly involve objective criteria that law enforcement can assess, the individual's race does not hold valid weight in forming reasonable suspicion, affirming the importance of fairness and legal standards in policing practices.
