It's *possible* I guess. There are two ways of looking at it. The first is that all you really have to do in an affidavit or complaint is establish probable cause (the 'more likely than not' 50+1 standard). The other way of looking at it is that you jam all the info in there that you can to make your case as strong as possible. I knew prosecutors who would have complaints that were a paragraph long and some that had complaints that were pages and pages long (in Wisconsin, we would do complaints and preliminary hearings as opposed to grand juries and indictments).
I was a little bit in between, where I wouldn't put EVERYTHING in there but I'd make sure I had my bases covered. And honestly, I don't know why anyone wouldn't err on the side of too much info without overloading it.
So yes, it is possible but it would seem strange, given the high profile, to hold that sort of evidence back.
I wouldn't want to speculate but...I am going to speculate LOL. I suspect the case is crap.
