How many points for dunking from the 3-point line?

[BillyMac]

5-2-1: A successful try, tap or thrown ball from the field by a player who
is located behind the team's own 19-foot, 9-inch arc counts three points. A ball
that touches the floor, a teammate inside the arc, an official, or any other goal
from the field counts two points for the team into whose basket the ball is thrown.

I'm trying to understand some posts. Some of you are saying that if the shooter touches the rim before releasing the ball, you consider him to be shooting from within the three point arc, and thus, it's only two points.

And, if the shooter touches the rim after releasing the ball, you consider him to be shooting from outside the three point arc, and thus, it's three points.

If a player, while holding the ball, jumps and hits his head (not the ball) (unintentionally, no advantage gained) on a basket support, is said player out of bounds?

I looked at the definitions (NFHS) of shooting and dunking. Shooting appears to involve throwing/tapping while dunking appears to involve forcing through the basket. By definition, dunking does NOT have to involve rim contact. The video of Griffin "dunking" appears to involve no rim contact with his hand. That NBA goal would be defined by the NFHS as a dunk. Billy Mac's 5-2-1 reference indicates that a "try" behind the 3-point line would count as 3 points. So, IMO, if someone jumped from behind the 3-point line and forcefully scored (dunked) a goal while touching the rim, it would count as 3 points. If the same situation occurred without touching the rim (still dunking by definition), it would count as 3 points.

Hypotheticals....gotta luv 'em.
