I'm curious about one scene in the movie. When Earl and Lucius are talking and Earl requested all data on the microwave emitter. Lucius made a wisecrack and Earl wants to fire Fox for what we later find out is because he was "asking too many questions". So I'm curious to why he was fired. Is it because Lucius said the usage of the emitter was illegal? Earl simply asked about it, why would he feel threatened by inquiries of Fox? Was he afraid Fox would uncover something? What am I missing here? Earl wouldn't have been doing anything illegal right?
