You seem to be the type to bash this individual because they are "against" natural treatment. There's a few things I feel you missed in your investigation.
1.) He is retired. And? Just because he is retired, does that mean that he no longer can contribute to the field of medicine? Him being retired means that he no longer wishes to see patients and so forth.
In addition, according to his website, his license status is Active-Retired, which means, as his website states, that he can prescribe medications for himself and his immediate family. You want to verify this, the link below links directly to the page of the Pennsylvania Department of State Bureau of Professional and Occupational Affairs License Verification page with Dr. Barrett's information.
licensepa.state.pa.us2.) You claim that Dr. Stephen Barrett has no other formal training other than psychiatry. Well, that MD states otherwise. There are two forms of psychological "doctors", psychologist and psychiatrists. If Dr. Barrett specialized in psychiatry and has an MD behind his name, then he is qualified to give advice about medicine and is considered a pschiatrist.
A psychologist is mainly a counselor/therapist. They have a doctorate degree (Ph.D) in psychiatric counseling. They are NOT licensed to issue ANY medications or drugs for use as part of a therapy. They counsel only.
A psychiatrist, such as Dr. Barrett, is a medical doctor whom has competed the necessary training to be come an M.D. and has gone through additional schooling and certification in the filed of psychology. A psychiatrist is licensed to counsel individuals using psychiatric counseling techniques (as a psychologist does) in addition to having the ability to prescribe drugs/medications to assist in the therapy. A psychiatrist is a medical doctor just as a cardiologist is a medical doctor (MD), except a cardiologist specialize in the heart.
3.) I didn't see anything on the website about him claiming to be a legal expert. Now, because of his years of experience he is what is known as an "expert witness." Is that maybe what you saw?
4) You continue to claim that Dr. Barrett is against alternative medicine. I don't believe he is. Personally, I am all for alternative medicine and a healthy and more cost-effective way to cure diseases. You have to admit, though, there are tons of snakeoil salesmen out there telling people that they have "The Cure."
As for your precious Don Lapre, I personally don't trust him. It has nothing at all do to with being for or against alternative medicine. It's simple, he's a con artist. I am a researcher and consumer advocate. Prior to the "Greatest Vitamin In The World" I watched Don for years on late night infomercials selling worthless make money at home packages teaching people how to "make millions" putting in classified ads. Once that operation went belly-up and he went bankrupt, he jumped on this vitamin kick, which is actually a multilevel marketing scheme. Don't believe me? Search this website for the name of Don Lapre. You will not only find people claiming his vitamin is a joke, but read about tons of others that got ripped off with his classified ad money making scheme. I believe what Dr. Barrett says about Don's vitamin being no more special than ones you buy off the shelf.
You also claim that it's because of Dr. Barrett's website that the vitamin might not be selling, because quackwatch.org is the first listing. Really? I just done a Google search on it. Guess what? The second listing (below is a Ripoffreport.com complaint (ripoffreport.com/reports/0/117/RipOff0117861.htm). Read a little farther down on the Google results. You'll find another link to another report on Ripoffreport.com. Reading a little more you will find a PDF document on the FDA's (Food and Drug Administration) website where they sent a certified letter to Don Lapre in regards to false claims he had on his website about what the vitamin could actually "cure." Are you now going to blame the FDA and Ripoffreport.com for the failure of this vitamin scheme? You can read that letter on the FDA's website here:

In addition, these "cures" are something you are putting in to your body and consuming. You don't want to go mixing natural medicines and not knowing what they are. Therefore, I see nothing wrong with Dr. Barrett debunking frauds. People get too relaxed because something is "natural." People seem to get too trusting of anything "natural." Natural cures, such as herbs can have just a deadly effect as any chemical drug.
You can just as easily have an anaphylactic reaction (sever allergic reaction) to an herbal supplement as you can a synthetic chemical drug. I am sure you have heard of the poison Hemlock. Well, that's natural. Just as there's certain chemicals and medicines you don't mix for the possibility of them interacting negatively, the same can be said for herbal remedies.
5.) Finally, you rant about Quackwatch.org not releasing the public information as it is a "non-profit" website. The website does not claim to be a registered non-profit organization. You can start your own non-profit organization or business. Heck, I am in the process or redoing my non-profit website, which deals with consumer advocacy. It is non-profit as I don't charge people any fees. People will have the option to "donate." BUT... I do not claim, nor does it seems that Quackwatch.org claims to be a "registered" non-profit organization.
The difference? Anyone can have a non-profit cause. The difference is in the advertising. Non-profit organizations that allow you to claim your donation on your taxes are registered with the federal government as a non-profit organization (that is, 501(c)(3) ). People that donate regularly and use those tax exemptions look for that 501(c)(3). Now, if Quackwatch.org was advertising on the website that they were such, then that might be an issue.
Furthermore, since it appears that Quackwatch.org is NOT a 501(c)(3) registered non-profit organization, they are not bound to release any financial details to you. It is only 501-registered organizations that are bound to release such information to the IRS and the public.
I hate to sound obtuse, but I would highly suggest you read and research a bit more before you jump on the debunk train. I commend your efforts on wanting to push more people to use natural cures, but I don't believe bashing people that have other's health at their heart to be a good way of doing so. It seems to me that Dr. Barrett is looking for these snakeoil salesmen and is finding them.
