No matter how bad the lead defense attorney is in this case the case will not be overturned on appeal because of it. IMO. It is much harder to have a case overturned than many may think and he has four lawyers so he is well represented.
I read about another murder defendant and he used that excuse to appeal saying he had a crappy lawyer (more or less lol) and even produced photos of the defense attorney sleeping through some of the testimony in court. His appeal was denied and the appeal court said that even though at times his attorney may have dozed off he gave the defendant good representation when cross examining witnesses for the state and in the defense's CIC.
When cases are overturned on appeal most all of the time it is due to a ruling/s the presiding Judge made that was so egregious it could have changed the outcome of the trial. I think this Judge has been extremely fair and has given the defense a lot of leeway when cross examining state witnesses. Sometimes way too much leeway and way too much time, imo.
So if he is convicted I do not believe his case will be overturned.
IMO
