The burden of proof that an article was originally purchased from the person accepting or receiving it, that it was the first subsequent sale or exchange thereof to a person other than an ultimate consumer or that it was a first sale at retail of such factory-rebuilt merchandise shall be upon the person asserting the same. Evidence of an existing trade practice in the Town of North Hempstead, if any, shall be admissible for the purpose of determining whether or not merchandise is in new or used condition.
This chapter shall not create any liability on the part of the Town of North Hempstead, its officers, agents or employees, or the officers, agents and employees of the appropriate police agency, for any act or damage caused as a result from reliance on this chapter or any administrative decision lawfully made thereunder.
It shall be the duty of any police officer of the appropriate police agency to require any person seen dealing in secondhand merchandise, and who is not known by such police officer to be duly licensed, to produce or display his dealer's license and to enforce the provisions of this chapter against any person found to be violating the same.
