It's only illegal if you do it

Congress is getting ready to give the MPAA and RIAA permission to hack your computer if they suspect you might have copied music or movies.
They'd get immunity from all state and federal hacking laws, and if they went in and trashed your computer for any reason, whether you had copyrighted material or not, you'd have to get permission from a U.S. attorney general before you could initiate a (long, expensive) lawsuit, and you would have had to have suffered at least $250 in damages to even be eligible.
