Need help to resolve a protest

[nine01c]

Personally, I feel this is akin to yelling FOUL! then realizing "Oh, @#$%, that ball is FAIR." Well, once you have yelled FOUL! that's the call you must stick with (and just hope it was a close one). Except for, perhaps a posible Home Run, runners and fielders can't be told FOUL then be expected to adjust to the change to FAIR. Yelling Batter's OUT! seems unchangable to me.
