We don't know the facts yet.
I guess Mrs. Stone's son will be testifying about what he heard, too. It won't just be the word of one woman against three men. There are two witnesses to what the men were saying.
The men should have stuck with the "Just-joking" story, because now, when Eunice and her son testify about what they heard, the young men will have to think up yet another excuse.
They are going to run out of excuses eventually.
Well let the Feds, or FL or GA, charge them with making terroristic threats and it can all come out in the trial.
Of course I take with a grain of salt their testimony on a Bible "to tell the truth the whole truth and nothing but the truth"
