So long as JB comes to the court with a clearly expressed need, he will get the investigative funding. This was made clear by HHJP from the beginning. The initial budgets could be expanded so long as specific need was shown. JB has a list of "witnesses" he wishes to pursue. Even the state agrees these are real people with some connection via TES searches. This time JB did ask for funding properly, for a clear investigative task.
HHJP assigning the extra funds is actually the cheaper option for the state. Spending relatively inexpensive "investigative" funds now, greatly reduces the chances of any viable or reasonable appeals later on sudden "new evidence". It also all but eliminates claims of ineffectiveness of council.
The Judge is not looking to do what we want or convict KC. he is looking to run a fair trial with the absolute minimal chance of reversal on appeal. That means he often will have to accommodate some of the less outlandish requests from the defense teams. He will also be using a very diferent touch now during pre trial activities. The Judge will be very accommodating of the insanity, while at the same time putting forth some subtle and some not so subtle warnings should either side be straying close to the line. This is in part to avoid any concerns of pre trial bias. Remember it is KC on trial not her defense team. Once the actual trial begins and these players are standing before the judge and jury presenting the full case the gloves come off and all players will be expected to behave and perform in a professional and legally appropriate manner.
And for all of our outrage over OMG he gave them more money. Really if you look at it in the big picture, The State of Florida is actually getting off fairly cheaply in this one. The judge and the JAC are keeping a very close watch on any and all costs and making the defense fight for ever dollar, thereby keeping the costs tightly controlled. Much more so than we think just from watching these little interplays. For comparison look at the Brian Nichols DP trial in Atlanta, and what it did to that states indigent defense budget.
If left to his own devices JB and company would be spending thousands of hours on investigative time. But through this careful alotment of small pieces the judge is keeping those costs lower and insuring that there really is alot less fishing or waste than we immediately perceive.
