I am no huge fan of Frist’s (as a politician. As a man I think he’s a pretty admirable guy). My guess is that this stock sale stuff will ultimately fizzle out, mostly because I doubt Frist is so stupid as to do what some allege. But I see nothing wrong with the appropriate agencies investigating Frist’s blind-trust stock sale. If anybody sees a good argument why it shouldn’t be investigated, I’d be curious to take a look. But as far as I’m concerned, it sounds like the right thing to do in a fairly no-brainer way. If he did something wrong the investigation is obviously warranted. If he didn’t, the investigation should clear him. Exoneration is as important a function as conviction.
