Editing Probable cause (section)

==Consent to search==
{{main|Consent search}}

If voluntary consent is given and the individual giving the consent has authority over the search area, such as a car, house, business, etc. then a law enforcement officer does not need probable cause or even reasonable suspicion. If the person does not give voluntary consent, then the officer needs probable cause, and in some cases, a search warrant may be required to search the premises. Unless another exclusion to the fourth amendment of the US constitution occurs, when the person withdraws their consent for searching, the officer has to stop looking immediately.<ref>Lemons, Bryan R. “SEARCHING A VEHICLE WITHOUT A WARRANT” Web. 30 Nov 2014. https://www.fletc.gov/sites/default/files/imported_files/training/programs/legal-division/downloads-articles-and-faqs/research-by-subject/4th-amendment/searchingavehicle-consent.pdf</ref>
