Good read.
As we know many peculiar things can happen.
That said Umpires cannot always interpret intentional or not.
There are Players who do know what they are doing on the field. Intentional or not.
Umpires could no humanily way decifer all of that correctly all the time.
Did like the post who commented maybe throw out a flag...that would be interesting.
Intent can be tough. If I am not sure, then I am calling no intent because I can't read minds. It is why the NCAA rules committee is taking more and more grey/intent areas away. See previous discussions on hit by pitch and obstruction - the rules in college are it either is or isn't based on what happened - intent is no longer part of it. The pitch hit you or didn't - I no longer need to judge your attempt to avoid. You either have the ball or you don't in obstruction. And so on...
And as you have seen in other discussions - intent is not actually a part of many situations that many coaches/players/spectators (and some umpires) think.
If a player can decide in a split second to intentionally interfere, AND make it look like they didn't intend to do so based on what runners and fielders are doing behind her... well good for her. Seems unlikely though.
I am sure there are more realistic scenarios where I guess this could happen - but most players (and coaches) who think like this are not as clever or as sneaky as they think they are.
