It comes down to credibility. He’s proven he will lie to save his own behind. It stands to reason then, if he pleads not guilty and this goes to trial, that he will continue to lie to try and save his own behind. His very freedom and/or his very life will be at stake. He has every reason to continue to lie.
He proved on his front porch he’s willing to do just that, so why should anyone believe him now? Nothing has changed, in fact he has even more reason to lie now. Now they have evidence against him. He needs to lie even harder.
He has no credibility. He’s not an honest, decent, upstanding citizen. He never even called 911. He was having an affair. He dumped his babies bodies in oil to hide them. He only gave this “story” when he had nowhere else to go, as LE linked him to to the disposal.
It’s not like he came forward with his “truth” of his own free will, he only presented this story when he was backed into a corner.
He gives me no reason at all to believe he’s telling the truth now.
