This requirement is intended to protect individuals from arbitrary governmental intrusion into their personal privacy and property. The combination of reasonable suspicion for brief stops and probable cause for full searches ensures a balance between effective law enforcement and the protection of constitutional rights.

Other concepts, such as consent, play a significant role in searches but do not establish the foundational legal standard. For example, while an individual can consent to a search, that consent is distinct from the probable cause necessary for law enforcement to conduct a search without a warrant.
