#1. Another defense will cost him at least another million dollars.
#2. His witnesses are now locked into their testimony, which the DOJ and Fox, etc. will now have months to discredit.
#3. The public hates mistrials. The jury pool will be even more against him next time.
Smart defs cut a deal after a mistrial. Stupid ones get convicted the second time around.
1. The prosecution gets an opportunity to fix its case.
2. The prosecution does not go forward with on a new trial in many cases where it determines it evidence is too weak.
This case may very well fall into the second category.
