Richardson was Inslaw's attorney during their dispute with the Department of Justice over the Promis case management software for prosecutors. That case was arguably the only Promis scandal with any basis in fact. It became widely know after a series of articles in Barron's. They got their day in court and lost.
The later descriptions of Promis from Skolnick, Grabbe, et al gave it incredible powers to crack into any bank account anywhere and grab the money, detonate computer chips embedded with tiny thermite explosives, use a secret chip built into mainframe computers to upload data up to spy satellites, etc. A surprisingly large number of gullible people actually believed that stuff. It's fiction - taken from an novel written about the NSA before the existance of the agency was officially acknowledged.
Mossad wasn't responsible for that one....MI6 did it. Even his wife was skeptical. The Israeli autopsy disproved it....and Maxwell was buried on Israeli ground...unlike Safra. If he was on the outs with Israel that wouldn't have happened.
Makes me wonder about Thomas' affiliations.
