Erin Brockovich and Lois Gibbs generated outrage, which was well deserved and a societal good. They were working against unregulated/underregulated firms, which did not have effective oversight. Oversight for PG&E should have come from the US EPA. I suppose the EPA should have handled Love Canal too, but the agency didn't exist when Hooker dumped their pollutants. Your cultural references suggest you're American, so…
This kind of dismissive attitude and condescending tone is a big part of why people don't trust people who say "trust us, you don't need to know what we're doing to those animals in the secret basement at the university." For the record I am not American and I have sat in on a few institutional review board meetings that pertained to animal welfare relating to a project that I was involved with.
I'm dismissive of and admittedly rather condescending to people who equate their ignorance to experts' knowledge. But that's the whole point: expertise isn't a hereditary title. It comes from study, and I support anyone's effort to gain it!
For what it's worth: if you've sat on an IRB you're not Joe Public. You may not be a scientist, but you're an expert in another field. You also know that, so I don't get what you're arguing.
