I don't have to look it up. I work in a DA's office. A SHOE is not a deadly weapon and Water is not a deadly weapon either. There may have been something IN the Water that made it deadly, but water in and of itself is not a deadly weapon.
I'd love to see your case where the spit of an HIV person was considered "deadly." Not saying that's not true, stranger things have happened. but the SPIT wouldn't be deadly. The virus would be, and if you had the intent to transfer the virus and you can prove that, then there's some justification for considering that a deadly weapon. Think about it like this... would the spit of a HIV free person be a deadly weapon?
