Ugly Situation - 3 point shot looking for feedback

[suntzu45]

I hope you all have patience with a rookie official asking probably some silly questions:

I worked a rec-league game last night (two man). I was the umpire.

I was the trail official, in this situation: team A trailing by 3 with less than thirty seconds to go. Team A player attempts a shot at the far side of the key from me. I see him "toe the line" and point to the floor indicating a two.

The lead official the referee, signals a three-point attempt. A conference ensues, where the referee insists he has the three. (how looking through all the legs and bodies is beyond me).

Here are the questions:

- Was this my call since it was in my zone?
- I deferred to the referee and scored the three
(correct or not)?
- Lastly, Is a player who is standing but squaring up to
the basket with the ball at his waist in the "act of
shooting" My call was yes.

I can't tell you how valuable this forum is, rookies in my chapter don't get much support.
