stupid mechanics

[crew]

i know i will catch grief for this, but what about these.
1. open hand on a violation. it says this is how you stop the clock, but every clock keeper in the world just stops it on the whistle. therefor no need for the open hand.
2. there is no mechanic for a hit on the arm during a shooting foul, except illegal use of the hands. some times this mechanic does not represent what actually happened. we(officials) are supposed to show the nature of foul. and no triping foul except for the block signal.
i also agree with the 10 sec freethrow violation count. personally i never count.
these are just thoughts.
