Protection from American lawyers?
I really feel for the chemical engineers who knew MTBE was a problem and tried to stop it. I've been in a similar career-limiting position.
My husband was the environmental adviser for ARCO marine in the mid eighties. He spent the year before the Valdez spill trying to convince BP and EXXON execs that the odds indicated that they were over due for a major spill and that they were totally unprepared to deal with it. He even ran a spill drill with almost the exact scenario that actually occurred six months later.
BP lawyers threatened to destroy him in court if he dared to testify against them.
