I don't think there was any child *advertiser censored* of Caylee. Maybe *advertiser censored* of KC sending pics of herself to boyfriends, and yes, that would make any father sick.
With that said, there have been cases where child *advertiser censored* charges were dropped or shoved to the side, to pursue the murder charges. Said *advertiser censored* would just be the clicking of photos on the net, not with a child in the home or even involved in the life of the accused, and the usual excuse that it was a used computer and the current owner had no idea. Also, child *advertiser censored* on the net is a Federal Charge, the Feds would not have let those charges go to the side if there were pictures of Caylee.
Now, if KC was just clicking on child *advertiser censored*, they may have shoved that aside to pursue the murder charges as the computer was a family computer and it would be difficult to completely prove just who in the house was looking at it. Especially since CA says even KC's friends used the computer.
As far as any evidence we haven't seen and want to? The psych evals (I know that cannot happen), the jail breakdown tape when Caylee was found, the home depot tape that was forgotten about in trial which may just be another bad check charge. And, I hope in the next case they have that involves tapes, that the State downloads the tape to a computer so that the one disc isn't the only way to access during trial.
