Due to the vagueness of state statutes concerning expandable batons, it is highly recommended that you speak with your local police department or an attorney to see whether or not these less-lethal tools are legal in your state, county or city. In many areas expandable batons fall under terms such as "sap" or "blackjack", for example.
