Book vs Excperience/thinking

[crazy voyager]

I jsut ran across this.
In the referee manual it says this
"When, a shot for a field goal, the ball is completly above the level of the ring, on its downward flight and before it touches the ring or it is evident that it shall touch it, an offensive player may not touch the ball (diagram 111)."

I checked the book, not a single word on offensive goaltending (FIBA doesn't give out casebooks so I couldn't check one).
How ever, I remember now, in the european championships, a player (offensive) caught a 3-point shot and put it in for 2, it would have coutned for three if he hadn't so it was stupid, but he was allowed to do that by the officials.
What should you trust? the book or your excperiences, there is another quote by the way

"During a shot for a field goal, a defensive player touches the ball while its on its downward flight and completly above the level of the ring, before it touches the ring or it is evident that it shall touch it. The trail official shall blow his whistle and indicate that two (2) points are to be credited to the shooting team (diagram 110)."

look at this sentence:
" touches the ring or it is evident that it shall touch it. The trail official shall blow his whistle and indicate that two (2) points are to be credited to the shooting team"

it says 2 points, it doesn't say anything about 3 point shots, either it should say something like:"the respective number of points (2 or 3)" or you should always award two points, even if the shot is from three. What do you say?
