There was a series that I was reading in the 90's where certain people had various psychic powers: some were Telekinetic, others were Telepaths and so on. The government required those with these powers to wear special identification to let others know.
I can't remember many details about the series but I remember one scene early on where a Telepath was confronted by some thugs in an alley. One of the thugs noticed his ID and said something to the effect that "I only have to make you make the first move and your advantage is gone." The guy mopped the floor with them because he also had martial arts training.
I know it's a long shot but does this ring a bell for anyone?
