I have some thoughts about how to effectively address the politicians who are the tools in this (note that Dodd would now be in good part a tool wielder rather than a tool, having moved to the other side of Washington's revolving door). However, talk's cheap, and I've restrained myself from posting them when I don't have any further, concrete steps to take or taken, personally, with respect to what I think might be effective. (I've communicated to numerous parties, including written letters to my legislators.)
As for his address, the MPAA office address is readily available. But I doubt anything would actually get through to Dodd. He's not interested in listening.
