A counterexample to the Gettier Problem

I wanted to do a presentation in graduate school on using Peirce’s Semiotic Grammar to counterexample the Gettier Problem, but things took another course. I believe I can formulate the counter example by pointing out the functional difference between a Rhematic Indexical Legisign, which is a demonstrative pronoun: this, that, these, those (those ten coins in anyone's pocket), and a Dicent Indexical Sinsign (an actual and determinate pocket of a correlating job recipient).

The ambiguity comes in the form of justification allowed: he who has ten coins. To allow a Rheme to do the work of a Dicent is obviously invalid, and thus unsound. It compels one to wonder what the academy is up too.
