Hmm, on the insurance thing, I'm going to venture that it COULD depend on exactly what kind of ownership Lex has over the Daily Planet. I'm assuming he's at least majority shareholder, but it's unlikely he's the sole shareholder, so he would have had to report to other shareholders on the insurance proceeds and, I'm guessing, distribute amongst them after all expenses related to closing out the DP are paid off. So he could have reported on only the smallest of the insurance claims, perhaps even claiming it was all used up paying any bills the DP owed, and then pocketed the rest for himself. THAT would certainly be fraudulent.
But then, I'm not an expert in corporate law, let alone how exactly insurance figures in there. I'm just extrapolating on what I understand about publicly shared companies.
Of course, bombing your own company and taking the insurance is fraud, obviously. But you have to prove culpability in the first place.
