Please explain how this trial is getting more like the OJ trial?

If you are referring to the media attention on the case then I would agree. But that would be the only comparison in my opinion.
The judge is controlling the courtroom, not the attorneys. As a former resident of Pinellas County. I can tell you that the county's residents take jury duty very seriously and in almost all cases of murder, they reach a verdict based on the evidence not emotion, unlike a Los Angeles jury. Friday's testimony by expert witnesses, including Dr. G the Medical Examiner, pretty much scuttled the defense contention that it was an accidental drowning. Combine that with the computer testimony and it is looking like Murder 1 for Casey Anthony and justice for little Caylee Anthony.
