They weren't in PUBLIC, where you and I and the rest of the world could see. If I said something in my home, in the presence of my family, I would hope not to see it published on the internet to further someone else's interests. I don't think it matters if Junior was present or not for this alleged gun incident; if Ron is making threats against others or himself, there are a number of people who could have intervened quickly. It interests me that Miller's story comes out now, when he has himself been somewhat discredited after this latest mess. I am listening now to Marc Klaas suggesting that Miller should be arrested for interfering in an investigation. He is also reminding everyone that his daughter Polly's mother slept through her abduction and did the Smart and Van Damm families when their daughters were kidnapped.
Regarding the road rage story, so far we just have the statements of the people who look bad as a result of DB's and Misty's behavior. We do not know what bad blood may already exist between Tim Miller and his crew and the Cummings family. Certainly, Ron is right not to trust Tim Miller, since whatever he tells Miller will end up in the media. And who's to say that DB would accurately represent anything Misty told her, or would go to LE instead of---to the internet? LE's best chances to resolve this case is if the amateurs stay out of it. The fringe players just keep the drama stirred up and are, for the most part, out for either their own aggrandizement or money, now or later down the road.
As to whether Ron is "innocent"--of what? I don't believe he murdered his daughter. Clearly, he is young and hot-headed, and he made a disastrous choice trusting his children with Misty. Now, he can either be distraught about his missing daughter and potentially enraged at Misty or he is in cahoots with her to cover up a murder. Probably not both. I pick door #1.
