Disconcerting Thrower

[mbyron]

Had a situation in a game last night: A1 shooting free throws, and B1 in the lane claps and says "I got shooter, I got shooter" just as he throws.

Rule 9.1.5 says: "No opponent shall disconcert the free thrower." I'm taking "disconcert" to be a "success term": the opponent has failed to disconcert if the free throw is good.

As it happened, the player (B1) did this twice, and the shooters made both shots. I signaled "delayed dead," but did not blow the whistle after the shot went in. I warned my partner, but said nothing to the player.

Question: did I handle this correctly?

I thought about warning the player, but maybe getting called for the violation would make a bigger impression. Frosh boys game, if that makes a difference.
