Read for yourself. Expecially the first paragraph. This article/post was writing by a physician from Cincinnati OH that attended this Riata lead summit. He expressed in the first paragraph his disappointment of how this is being handled by St. Jude. (his words not mine)
He also made no mention of people leaving early. Doesn't mean that they did or didn't. They could have very easily left early and been asked to take 2 minutes to fill out a survey before they walked out of the meeting.
I think the numbers in the article and the mentions of Durata lead and it's issues speak for themselves.
