I think it was about JA's need to: feed on the drama, be in control, wrest media focus away from and rob the Alexanders of the overwhelmingly sympathy they received after their VIM's spoken just hours earlier.
But...I also am guessing it was her idea of strategy. That she planned or is still planning to say in allocution that SHE is not the one sliming Travis. That she's done everything in her power, including testifying in secret, to keep Travis edified in the public eye. After all, it is not HER responsibility what her attorneys ask DT experts, or her. The YOU-MADE-ME-DO-IT sliming has been one of her most consistent story lines, from Flores to family letter to plea-threat to guilt trial to interviews afterward, to her blog. I expect to see her trot it out one last time....
