IANAL, but isn't it perjury, or at least something subject to civil sanctions, to attest to facts in this manner without personally performing enough due diligence to ascertain the facts are at least probably correct? The Bar Association should be interested in its members signing-off on legal documents they have not properly vetted. Perhaps the best course of action is an education campaign directed at the States' Bar Associations.
