I really don't think JB is intentially being inept. He is just very inexperienced, took on too much, has a big ego, and thinks he can handle it. Strickland and Perry asked ICA if she was happy with her counsel several times and she said "yes". I think she kept him on because he fell for her lies. You have to remember that many defense attornies will never ask the client if they are innocent or guilty. They will ask the defendent what happened and go from there. In the end, especially in a case like this, all the defense can go on is what the defendant has told them. Then try to debunk the state's evidence.
JB really shouldn't have dragged others into OS. He should have kept it simple. Painted a picture of a loving mother that made the mistake of answering the phone while Caylee was in the tub and she drown. ICA went into panic mode, the shock took over, the lies started (starting with calling CA to babysit) and it just got out of control. Explain that she had a very low self esteem, became terrified of disappointing her parents. Which could explain why she has lied so long about being pregnant, having a job and stole so she would have some income. He could have said that after Caylee was born, ICA loved her so much she couldn't bare going back to work and be away from her so she lied about having a job. The duct tape? After Caylee passed. ICA gently wrapped her up in her favorite Pooh blanket. Put her in her favorite sand box (play house, whatever). Until she figured out what to do. She waited a day or two, thought a kidnapping would be her best story so she put duct tape on that poor little girl. It broke her heart to do that so she added to sticker with love. She then put her in the truck, drove her down the road and tried to bury her where ICA had buried all her beloved pets in the past. Was it the right thing to do, no. Would she take it back if she could, yes. Is this a case of premeditated murder, no. ICA loved her daughter with all her heart, she just made a series of horrible mistakes. Why did it take so long for her to admit this? She was too ashamed to admit her mistakes. He should also have said something to the effect that psychologists will be testifying to the fragile mental state, PTS, etc of poor ICA (many "experts" can be bought, find a few to testify).
Unfortunatly (or fortunatly however you want to look at it) JB thought it better to put blame on everyone else. GA found Caylee, gave the body to Kronk (? that one baffles me), ICA was afraid of GA because of abuse, etc, etc. He should have focused on one person and one person only ICA...Would this help her get off scott free? Probably not. Would this help her avoid 1st degree murder? More then likely.
Sorry, this ended up being much longer then I expected...
