Richard Forno writes on Vigilante DRM:
If it passes, the Hollywood Hacking law, as Berman's bill has come to be known, would give a profit-driven industry license to do what the government cannot: conduct searches of personal property at any time without the case-by-case justification a search warrant requires. In other words, the constitutional protection against unreasonable search and seizure is abrogated, thereby negating the users? implicit guarantees of privacy and confidentiality. More frightening, these non-government, for-profit entities would be free to disrupt personal property (namely computers and networks) in their attempts to "enforce copyright" - too bad if legitimate data or activities are affected by such enforcement activities.
