He's primarily an engineer. A VERY good one who's designed a lot of music-related equipment that changed the sound of music over the last couple generations. As to law - well, he's been in lawsuits now since the second album, so I imagine he feels he knows more by now than your average lawyer. :)
Yeah, control freak is putting it mildly. After he got enough money, he made a home studio in his basement so that he could control every aspect of the music from that point on. He even went from using off the shelf parts to designing his own, which has ironically made him a LOT more money than the music ever did. This lawsuit is but one of many he's fought, putting legal control in the list of controls he's anal about.
There's never been a better time to be a liar! Between celebutards inventing fictional histories to scam the ignorant, lawyers filing patents lying about things they supposedly invented, lawyers filing harassing lawsuits over supposed file sharing, bankers lying about investments and loans, Hollywood lying about movie profits, big companies using international laws to hide profits, Collection Agencies lying about fees for artists, politicians lying about pretty much everything, coupled with the widely broadcast persecution of whistle-blowers, what exactly are we telling our children about telling the truth?
Now if you will excuse me, I've got tax forms to fill out.
Think about it a moment - the only way you can enforce a ban on ballot selfies is to have police INSIDE the voting booth to make sure you don't take the picture. This is about keeping police inside voting booths in an effort to discourage certain categories of voters.
