There are continuing sales of the product to police departments throughout the U.S.To be accommodating, Ms. English has voluntarily and without charge installed the product in the firearms of those police agencies.She realizes as sales increase that this accommodation will either have to be eliminated, or that a charge will have to be added to the overall price of the product.She is thinking of distributing the product with an "installation manual."The product itself is sturdy, and installation simply involves attaching the product on the weapon near the firing chamber.She has concerns, however, that someone might improperly install the product and thus interfere with the original design of the weapon.She fears that this may cause a malfunction such as "jamming."What are your thoughts?What should the installation manual include?What, if any, legal issues are presented?Ms. English would also like you to advise her as to other ways she can reduce her liability so please advise her as to all possible options.While meeting with Ms. English about this situation, please also advise her regarding the law that applies here and how it applies to her and her product specifically.And, advise her regarding her possible defenses, if any.
