The Washington Legal Foundation's web site has, available for free PDF download, an excellent study of the silica fiasco. Authored by Philadelphia attorney Nathan R. Schactman, the study exposes the absolutely gross violations of both medical and legal ethics that prevailed in the mass tort Silica Product Liability Litigation. It describes the steps taken by District Judge Janis Graham Jack to unmask the fraud, and makes forthright conclusions about the appropriate sanctions for physician and lawyer shysters. A very good read!
