Wow. Compelling article.
Just one thing... the intro seemed a bit personal (like the journalist, David Gambacorta, is an ex-Witness himself):
"Stephen Lett is 69, bald, and round-faced, with eyes that sometimes spring open to dramatic effect while he’s talking — if you can manage to get an audience with him."
While personal descriptions are good for effect in creative narratives, I don't believe they translate as innocuous in a newspaper, such as The Daily Inquirer. But that's just my personal opinion.
I think the story and facts alone hold enough shock factor. There wasn't really a need to highlight Lett's more negative appearance to add weight to the article.
