A few questions

[Official]

Had a situation the other night. Team A fouls team B. Team B's player is hurt a sub goes to the table to check in as player B heads toward the sideline. Just so happens team B is in the 1 and 1 bonus. I asked player B if she was okay to shoot the free throws and she did. Now what would I have to do if player B thought they were in no condition to shoot the 1 and 1?

Had a situation the other night where team A is clearly violating the baseline on a throw in. I didn't call anything because I wasn't sure how to administer it
Do I go to the table and report a team warning and each additional violation is a team technical?

Still a little confused on hand signals. When I am the trail official on a free throw. I understand to give a hand count away from the shooter. However do I put my hand up when the shot goes up and chop it down to signal the clock to start if necessary or to signal a point scored? If i'm a trail official on a throw in in a teams front court do I have my hand up and chop the clock along with the lead official?

If I'm a trail official in the back court and the ball handler is clear on the other side of the court is it okay if I move in towards the center of the court to get a better view or should I work the sidelines?

I see a lot of situations where Team A player will shoot and team b screens them out after they shot but before their feet hit the ground is this a shooting foul?
