I know a woman who is mentally unstable. I will not go into details, but she basically has not functioned socially for years. As insane as she is, she at times has pulled off some amazing feats. She still owns her own home, but as far as I can tell, has never had a real job in her life. At one point, her kids came to us to help take care of a number of properties she had acquired illegally in their name while they were minors. Insane people do not think or act like sane people, and as a result their drive and willingness to do what ever it takes produces results that the rest of the world views as impossible. I have no double that given the amount of planning and research and effort he likely put into this, that he could have found a way to get the mailing accomplished.
