I saw.
Under normal circumstances I could easily see a judge denying the warrant based on the "fruit of the poison tree" doctrine.
I don't think that doctrine applies.
It might if the original seizing of Wiener's laptop was illegal or otherwise improper. I don't think that's been asserted. So no "poisonous tree".
If you have a lawful warrant to search for something, in general anything found is evidence, even if evidence related to another crime.
But there are limits. The example sometimes given is that if you're searching an apartment for a stolen elephant, you can't start opening drawers. Anything found within the drawers would be inadmissible, since they were beyond the scope of the warrant. But find a stolen horse, and it could be lawfully seized.
Caveat: I'm clearly not a lawyer, and will yield to anyone with a deeper understanding of the concept.
