To reach or not reach

The obvious first response is: why are you looking there?

But since we sometimes see things, in the first case, can you be absolutely positively sure that the defensive player didn't touch the ball, causing it to drop? If you didn't see that play from a perfect angle and cannot be 100% sure of what you saw (not what you think you saw), you should let your partner live and die with it.

Second case, again you need to be 100% certain you saw it, and then I would only ever call it if I thought my partner was screened from seeing the kid's knee.

If it's a veteran partner, I'm letting him live and die with it. You shouldn't even be looking there in the first place.
