IIRC, LE said Sawgrass was required by law to keep security video for several days. That does not mean they cannot voluntarily keep it much longer, if they so choose, such as was noted earlier, for liability purposes.
IIRC, there was mention of obtaining security videos in the 400 pages but I don't care enough about this to look up from where and when. As another poster suggested, I can understand security video on stairwells, but even if there weren't any focused on the apartment, I am confident there were cameras on the entrance Casey must have used to get there and by her own description used.
IIRC, the detective also said they had contacted everyone or
tried to, which again, I don't care enough to go look for the exact quote but suggest OP review the tape.
As has been repeatedly pointed out, LE is allowed to lie and if they did or stretched the truth, they are well within the law. I doubt very, very much they did in this instance. They had plenty without it and were trying to get more information from her by confronting her with proof of her obvious and repeated lies.
I find it disheartening that anyone would try to discredit LE, especially as they have been so very diligent in this case, imo. This to me is not unlike Jose Baez questioning the results from the Body Farm. Even if the Body Farm disclosed to him they were not done with their testing, it does not mean they have not completed any testing. I find it highly doubtful LE would open themselves up to at the very least, monumental embarrassment, if they had any doubt about Caylee's tragic death.
