Is consent withdrawn if a suspect who has given consent to search his car's trunk decides not to cooperate with the police?

"Although actions inconsistent with consent may act as a withdrawal of it, these actions, if they are to be so construed, must be positive in nature. Thus, if a suspect who has given consent to search his car's trunk throws the key in some bushes, his consent is withdrawn [citation]. Similarly, if a search is agreed to, but the suspect later refuses [168 Cal.App.3d 1068] to cooperate with the police, there is no consent [citation]." (People v. Botos, supra, 27 Cal.App.3d at p. 779, 104 Cal.Rptr. 193.)
