I totally agree with you. I have wondered why she would sit in jail and not attempt to make some deal with an accident defense.
I'm grasping here - perhaps the reason FCA would sit in jail for three years without a word on the phony drowning or accident theory, is that when planning her defense, JB told her that she would at the very least do 3+ years on the 4 counts of lying to officials. There was no way to get around the fact that she lied to LE on the 4 specific incidents, now that they planned on saying Caylee died in an accidental drowning. Perhaps thats why they delayed the trial so long, to hit the 3 year milestone. Then, on the billion to one shot that she would be found not guilty on the major counts of murder and only guilty on the 4 lying to LE, she would get time served. We all know how that worked out for FCA. If I did not watch this happen with my own eyes, I would never believe it.
