And that's one VERY good reason not to pass it. 844 pages of obfustication means the law will allow just about anything. If I have 844 pages to look in, I can find words to cover anything I want to do. Long and wordy laws grant bureaucrats freedom to do as they please.
The "gang of eight" should be told to boil it down to no more than ten pages, single spaced. Then at least we would know what we are getting into.
