On November 29, 2010, Greenpeace filed a lawsuit against two major
chemical companies, their PR firms and several individuals for activities
that amount to corporate espionage. Chemical companies Dow Chemical and
Sasol (formerly CONDEA Vista), through the PR firms Dezenhall Resources
(Nichols Dezenhall at the time) and Ketchum, hired private investigators
from the firm Beckett Brown International (BBI) to spy on Greenpeace from
1998 to 2000.
