Part 2MINORS CROSSING THE MEXICAN BORDER
Section § 1500
This law gives peace officers in California the power to stop people under 18 from crossing into Mexico if they are alone and don’t have a parent’s permission or a passport. However, officers can only prevent them from crossing the border; they can't hold them for any other reason. The law doesn't affect any other powers an officer might have.
