Would the 'unreasonable search & seizure' amendment apply to people's files?

I would speculate: no. Once something was uploaded to megaupload, it was made available for download to anyone with the url for the file.

If the file is public, its going to be very very hard to successfully argue that a LEO looking at it constitutes an unreasonable search.

There may have been no comfortable file navigation tools built into megaupload, but I believe they would still be considered 'public' by nature of the fact anyone could download them.

edit: I'm assuming that the public nature of the files would be the best choice to argue that it is not a unreasonable search. Of course there may still be reasonable searches if they're not public, but I think one could make a case that the files were public. Is this what you're disagreeing about?
