By definition, trial judges approve the instuctions they deliver to the jury. Moreover, the "reasonal explanation instruction" does exist and is most certainty used across the nation.
Prior to Judge Delucchi delivering jury instructions in Scott Peterson's trial, I recall going through this exact debate with other disbelievers, naysayers and/or doubters. However, when Judge Delucchi finally instructed the jury, the "reasonable explanation instruction" was included. Specifically, it was covered in instruction #39, which read: "If the circumstantial evidence as to any particular count permits two reasonable interpretations, one of which points to the defendant's guilt and the other to his innocence, you must adopt that interpretation that points to the defendant's innocence and reject that interpretation that points to his guilt."
That doesn't mean jurors are supposed to throw common sense out the door.
There has to be an alternative to the prosecutor's theory that "could" have happened. I haven't heard one yet for the duct tape.
And it isn't like KC can deny knowing Caylee was dead. KC was borrowing a shovel the day after the last time Caylee was ever seen. Then KC was texting to Amy about her smelly car that coincidently has a big stain in the trunk. There's the used paper towel used to wipe up cadaver remains in trash that came from Tony's apartment. There's the car that got ditched right before KC was supposed to take Tony to the airport that KC didn't file any stolen car report about. There's the heart sticker like the ones in KC's room and like the ones KC plastered all over pictures of Caylee. There's the skeleton pictures KC downloaded after Caylee's death. The beautiful life tattoo. The "Everyone lies, Everyone dies" poem left on KC's myspace for Cindy.
And then when confronted by her mother, KC doesn't claim there was an evil kidnapper. She says a loving nanny is taking good care of Caylee. She'd talked to Caylee that very day and Caylee was just fine..."Lets not upset the baby...she's napping. Give me one more day."
During the first bond hearing Yuri testifies on the stand that KC didn't tell even HIM there was a kidnapper at first. He said KC said Caylee was with her nanny. KC'd even talked to Caylee that day and Caylee was fine. Only then Caylee's was found and she hasn't been fine since the last day George saw her, And that peskily impeaches KC's story about Caylee calling on July 15.
I don't think KC's obvious lies to mislead LE are going to sit well with jurors.
KC had motive---there are friends that will say she complained about her mother duties.Casey's new boyfriend just wanted boys. And instead of dumping the Tony Casey instant messaged her friend that Tony was worth any pain or sacrifice because what was there could be so great. There was alsothe rivalry for control over Caylee between Cindy and Casey. The one KC couldn't let her mother win.
KC had opportunity--The last time Caylee was seen she was with KC. JC's pings show she spent the afternoon at her parent's house with easy access to the Pooh blanket, the trash bags, duct tape, heart stickers and the Anthony laundry bags. By the time KC left her parent's home and headed for Tony's on June 16, Caylee was gone.
Maybe there isn't a video of Casey doing it or a confession, but I think the evidence in this case is powerful. Before Casey's trial is over, with her phone pings and the pictures of KC out searching and doing her stakeouts at Fusian the prosecutors case will become as clear to the jury as if they'd been watching a high definition movie on a plasma tv.
