My first thought when reading the headline. It's not "illegal texting". It's the crimes they do via texting (or via any other communication medium) that are illegal.
Also, I thought the government already didn't care about any of the bankers' crimes, because it never seems to prosecute them. If there are banking crimes committed out there, I'm sure the NSA (and now 16 other agencies [1]) are aware of them, even going back several years. They just choose not to prosecute them.
