Do you make a call here?

[AK ref SE]

I throw my two cents into this.......Game management comes into play, whether it is consider praticing or not! IT is covered in the rules (some will not agree(my opinion)). Just like contact is a foul if you read the rule, basically any contact on the person with the ball. Do we call all contact? NO! We each decide what amount of contact is consider a foul and what isn't. We each must decide what we consider practicing or not and handle it accordingly.
I would tell the player that what he/she did was not appropriate, would not say anything more!

I would say what the FT shooter did was practicing. In the spirit of the game or rules I would warn the Shooter!
