I wrote out a long post and decided to delete it as it wasn't necessary.
I've come to the conclusion she will testify in the hope of avoiding sitting on death row at Lowell Correctional. I don't think she wants to take a chance on going to this place as a death row inmate.
That's my final call - Casey Anthony will take the stand.
IMO
Ya, I've come to the opposite conclusion, based on the same considerations.
I really can't see it happening. I also think there is a lot of wishful thinking behind speculations of her taking the stand. --Law & Order style, 11th-hour confessions, "You can't handle the truth!" and all that.
I'd love to see that, just as much as everyone else (except for maybe the news media, who seem to be the major proponents behind this theory --Can you imagine the replay value??). I'm just pragmatic about the way these things normally play out.
Ultimately, Casey knows she is guilty. She might fancy herself as a master-manipulator, and the smartest person in the room, but she is definitely calculating the risks of attempting an epic, coup de grâce of insanity and lies in front of the entire world. If she slips up on the stand, it could literally cost her her life. I don't think she has the minerals to put herself in the hot seat. Casey is an evasive liar, an artful dodger, a sneaky-snake, not the criminal mastermind that she has be characterized as.
That said (and I apologize for rambling a bit, the coffee is just kicking in), I really hope that I am wrong.
