JG said that Lee said that Cindy said there was a big fight...so any testimony from JG or Lee that a fight occurred would be hearsay. BUT the SA could ask Cindy on the stand if there was a fight, and if she denied it they could say, "didn't you tell Lee there was a fight?", and if she denied THAT they could call Lee to the stand to testify to Cindy's "prior inconsistent statement"--i.e., that there was a fight. Hearsay problem resolved.
And if Lee denied that Cindy ever said that, they could say, "But, Lee, didn't you tell JG that Cindy said that?" and if he denied THAT they could call JG to testify about Lee "prior inconsistent statement"--i.e., that Cindy told him there was a fight...
