I think you are missing my point.
Civil vs Criminal cases dude, you're imposing some aspects of criminal
cases upon civil proceedings and that's not how they work. In a
criminal trial it's a dramatized version of reasonable doubt, civil
proceedings must show 51%+ responsibility on the part of the defendant
(much, much easier and why the powers that be choose this route). Not
to mention it's their content (no harm, no foul on downloading
something they already own)
and MPAA/RIAA/blah have set precedence for proactively tracking (either themselves or appointed parties) file-sharing events (method of access is not unlawful and cannot be brought into contention...is BitTorrent inherently illegal when used for legit purposes? -- nope).
If bb knocks on your door then you argue evidentiary process otherwise in a civil proceeding you bear more of a burden to show you *didn't* do what they're claiming (right or wrong they do have the legal upper hand with their records versus essentially a verbal denial at best).
