The Sheriff, or any of his deputies, may impound and retain possession of any bicycle that does not have affixed thereon a valid indicia until an indicia is obtained by the owner of said bicycle under the provisions of this chapter or under the provisions of any applicable city or County ordinance wherein the owner of said bicycle resides.
Also:
Every bicycle, when placed or left unattended on or in any public place, shall be securely locked by the operator thereof.
Further evidence that every one of us violates countless laws every day, giving ample justification to anyone in law enforcement who wants us to have an unpleasant day.
