Except that it was Cruise's attorney, not him, making the comment. And I tend to agree with the attorney on this one. Drew P. kind of pulls a name out of the blue, links him to a questionable quasi religious organization, and then implies a diagnosis.
Even if he guesses right, it's a bit unprofessional to make these kinds of comments. People are understandably a little touchy about being called crazy by board certified doctors because it migth have more (undeserved) credibility than if, say, TMZ ran a story calling you crazy.
You'd think that the doc would be a bit more judicious with his purported diagnoses is all.
