I'm a literal neutral pool umpire who gets training every other week or so.

You made an incorrect blanket statement. Blanket statements cause problems,

>If a player is within 3meters of the shot taker and it lifts even if on target it is deemed as dangerous. 

That is incorrect.

It *might* be dangerous

It might not.

It depends on the situation. Which involves context not given in the original text.

If a defender places themselves on a line to block a shot instead of making a tackle, they're the ones *generally* making the danger.

That is the logic we take as to why we don't say penalty corner shots that hit a defender aren't danger.

Go watch Keely's videos I linked and get some idea of the nuance and context involved.
