A) I was vociferously castigated for calling this violation on bench personnel at a camp two years ago (I thought one of the clinicians had put them up to it to see what/if we would do anything about it). Was schooled that this violation is only for "players" on the court, though the rule clearly states "opponents." I wasn't in a position to argue the point, this being camp and all...then,
B) Consensus on this forum after that sitch was brought up in a thread was that this is better handled with 1) a warning, then 2) a bench T for unsporting conduct if they didn't knock it off.
That made the score camp clinician and forum 2, me 0. I'm still unclear as to exactly what of the two choices I would do should it occur again.
