Agreed, if you take each piece of the puzzle in isolation it sounds silly and totally not worth Johansson's time. But that's how most legal cases are: there's no one single piece of evidence that is conclusive proof in and of itself, there is a collection of facts that together form a reasonable basis for concluding a level of intent that meets the burden of proof.
I'm not convinced that the pieces all add up to a slam dunk, but you can't dismiss them one by one, you have to look at the whole.
