I was actually thinking of Crawley's bullying and/or harassing behaviour that we've seen from her towards patients. See parts of http://me-pedia.org/wiki/Esther_Crawley#Controversies_and_Criticism
I suspect that they are only concerned about behaviour of one researcher towards another member of the team.
Maybe they will eventually get concerned about researchers general ethical behaviour. I would be interesting if research funders sanctioned Bristol University because they had failed to deal with researchers who didn't get ethical approval
It does get very tricky. I imagine there must be plenty of examples through history of some genuinely brilliant scientific breakthroughs, benefiting many, where the lead scientist(s) may be pretty unpleasant. Academic genius and human decency are not necessarily co-existent.
Which makes it all the more important that the people employing such scientists don't put them in positions where they have power over others, and make it clear to them what behaviour is and is not acceptable, and take seriously reports of harassment, including bullying and sexual harassment, which is never acceptable, however brilliant the scientist.
And I'd suggest that a counter argument to this could be: the chances are strong that untalented bullies have prevented many breakthroughs from happening by unfairly suppressing more talented junior colleagues.
