Get the calls right? Responsibility?

[Little Jimmy]

I know were veering off the original thread here but why would the play TexBlue described be a violation of the lookback rule? If I understood, runner was moving toward 2nd (all be it slow), stops once, and then makes her decision to return to first. This is the same "stops one foot away from the base" situation I've seen discussed here before and there were a sizeable number who felt that no LBR violation had taken place. This seems like a decoy play gone wrong.
