You know this is an excellent point. My son cannot remember anything before or after his seizures by about 2 hours either way.
could this be the "only half the story" JB is planning to present as the major defense. Prior history of seizure and perhaps memory loss to account for KC either blacking out and finding Caylee drowned and then memory loss or panic setting in and details a fog so she made up the story? Defense teams can really spin a yarn. Perhaps the "seizure" was drug related but depending on when it happened. could also have been part of her overall planned defesne stratagey if killing of Caylee resulted in her being caught or just to explain any erractic behavoir and lies on her part. Its a good thing the her history of lying, long precedes her seizure claim.
Most likely it was all a ploy, just like describing the major accident and injuries of Zenaida and family in the phony car accident story. Her lies are always very grandious and over the top or a way to divert attention from her actions or to gain sympathy from others. It will be interesting to see how this plays out in the defense strategy. It just might show up. After all, they are grasping at straws to show their client as other than a totally manipulative lying sociopath.
