MediaSentry continued investigating in Michigan without license

An article by Ray Beckerman describes how MediaSentry, the "investigation" arm of the RIAA, has been doing so illegally without a license.

I think it is important for Canadian politicians to hear this, as they may agree with us that what MediaSentry is doing is of a far more serious nature than what they are investigating. I wonder if the major labels inability to find an above-board company that can provide evidence sufficient to win in court is also a factor in why they haven't bothered to file lawsuits in Canadian courts (for activities which are just as illegal in Canada under current law than in the USA).
