Afrosheen...
I'm really late to this conversation, but I did read most of the posts.
I appreciate your enthusiasm about getting a call correct...you know, for the integrity of the game etc.
Let me share a little story, that kind of goes along these lines.
Some years back, during the old two whistle days here in WA. state, I was doing an evaluated game at the "B" State Tournament. I was new L as the ball was coming from the backcourt to "my" frontcourt. The T was trailing the play around midcourt. I was already at the endline. I was "looking throug the players" (ball watching)
as I saw a crash around midcourt. The player that was dribbling had been fouled. My partner did not have a call...for whatever reason. I thought I would "save the crew" and make the call.
After the tournament...I read my evaluations. The evaluator said, "that while your call was correct, it is not your call, let your partner live and die with it." (I got to watch the championship game from the table as the Alternate Official) Who knows?
Anyway, this situation isn't exactly like yours...in that you were questioning a possible RULE error...while I was questioning JUDGEMENT.
I guess my point is...with many situations and experiences of approaching my partner...I have a general philosophy ...If I am going to ERROR...I am going to ERROR on the side of LET IT GO, TALK ABOUT IT LATER.
SIDENOTE: A lot depends on game situation, level of play, how far away I am from the play, how sure I am that my partner kicked a call, does my partner really need the help, etc.
Again, it sounds like you really do care about this officiating gig...that's cool.
