What Cindy is saying she did is, Remove the ladder from the pool because Caylee could climb it (preemptive), moved the box when she saw the possibility Caylee may climb on it (preemptive), put the lock on the back gate in a position it was impossible for anyone but an adult to access (preemptive) and then failed to keep locks on the doors or otherwise secure the exits when quite clearly from the photograph they provided, she was interested in opening the doors. Failed.
I have no reason to believe following "the dots" would lead me to any conclusion other than, Cindy would never take all those precautions and then not bother to secure the doors.
