It may be bad legislation, but I'm not sure how it is unconstitutional, since Congress is explicitly granted the power in the Constitution to establish copyrights.
Establishing the copyrights is one thing, no objection. The objection here is not to the copyright -- I'm a software author and musical performer who respects copyrights.
The objection is to a law which trashes constitutional protections against unreasonable search and seizure, invasions of privacy, etc. This is only incidentally about copyright per se.
