It would be ironic if one of Barry's competitors and /or enemies, bugged the Sherman home or if the house was under private eye surveillance around the time of the deaths.
Point is, it is possible that there is somebody, somewhere who is an uninvolved witness ( a spy) or has a recording of some type of the ghastly events that took place in the Sherman home.
rbbm. speculation, imo.
Drug Spies Piracy is the pharmaceutical industry's dirty little secret; fighting back has become its dirty little war. With the stakes this high, there are no rules, no conventions. But that doesn't mean there haven't been prisoners. - September 6, 1999
"The $300-billion-a-year pharmaceutical industry is mired in a hidden war with no boundaries and few rules. It is a war fought from behind mountains of litigation, one that pits the leading multinationals against a growing army of scoundrels who are either counterfeiting medicines outright (a criminal offense in which specific drugs are copied down to the form, color, and brand name) or peddling "bioequivalent" generics that infringe brand-name patents (a civil offense, but just as painful financially for the patent holders).
"Take any of the top 40 drugs," says Steve Smith, Flack and Whybrow's spymaster at Bayer. "All of them are being ripped off by somebody." From Argentina to Egypt to India, from Israel to China to Colombia,
drug piracy is booming. Companies in Canada and Mexico are big players;
even the Mafia seems to be dipping a toe in the pool. Not that any of that should be surprising, given the explosive growth in pharmaceuticals: Ten years ago a drug that generated $100 million in annual sales was considered a blockbuster; today $1-billion-a-year drugs are commonplace, and
"a kilo of an antibiotic can be worth more than a kilo of heroin," says Smith."
"For decades pharmaceutical companies have cultivated an image of obsessive purity to instill confidence in consumers, whose lives often depend on them. But
behind that vision of white-gloved chemists with their test tubes and microscopes stands a legion of secret agents like Flack and Whybrow, complete with black gloves and binoculars.
"The attitude of the drug giants is, 'Whatever it costs, just do it. Just burn everything to the ground. Destroy the enemy.'"
SHERMAN MURDERS: Did organized crime kill billionaire?
“Barry was a strange guy but he was perfectly nice to me,” Robinson told the Toronto Sun. “At the time he was under surveillance by private detectives"
‘Yin and yang’: Barry and Honey Sherman were polar opposites who devoted themselves to philanthropy
"In the early 1990s, as Apotex and its competitor, Novopharm Ltd., raced to manufacture the anti-cholesterol drug Lovastatin, Barry hired private detectives to rummage through Novopharm's garbage, looking for evidence of stolen trade secrets."
