Negative group delay times upon total reflection from frustrated Gires-Tournois interferometers seem to violate causality. Contrary to what has been recently argued in the literature, I show with the example of total light reflection upon an ideal nonabsorbing plasma that adding the time associated with the Goos-Hänchen shift does not solve the paradox, which remains open.
