Disconcertion From The Bench

Still an open question for me.
9-3c does say, "No opponent shall disconcert the free thrower." However, at camp a couple of years ago I did call disconcertion on the players on the bench for, after a warning on the first FT, continued to yell at the FT'er during his second FT. Was roundly criticized by clinician whose opinion meshed with the consensus on this forum: that disconcertion applies regarding players on the floor; unsporting T (perhaps after a warning) would be the only fitting penalty that could be called against those on the bench.
Given the wording of the rule, I do not agree with my clinician and with the consensus on this forum, so I guess I'm leaving it, for now, as an open question awaiting definitive resolution.
