Smart thinking there, Doc.
Before I start, I'd like to say that I'm consumately empathetic towards medical doctors and their ongoing battle with rising malpractice Laws. It really is a problem, one that is driven largely by frivolous lawsuits, greedy lawyers and misinformed patients. The end result, as stated in the article, includes a decrease in the overall quality and available quantity of medical care. Sad.
That being said, I think the guy making this proposal is at best being too emotional and at worst, losing his mind. He's proposing to refuse service to attorneys, which will inevitably cause them to react by finding loopholes in this concept and dragging all offending physicians into court, setting precedents in court, and creating yet more established routes for future attorneys to take advantage of people in the medical field. Unethical or not, it's plain stupid to draw up battle plans of this nature. Furthermore, one cannot ignore the fact that many malpractice attorneys fight for the rights of doctors, not against. By declaring war on others in their profession, however opposed they may be in principal, you will inexorably alientate the very people that will be in the position to fight for you if and when that dreaded Med Mal lawsuit arises.
Wanna cut MedMal insurance costs? Address the insurance companies that rake in the profit as well as the state legislature that maintains no-limit settlement practices(not all states do).
