By the 'expertise aside' part of my comment I think it's clear that sure, maybe the guy knows the technical stuff you wrote about. But, how a steel inspector in Norway knows about the HR practices and employee rolls of a rig in the Gulf, how much he knows about the expertise of the workers on that rig, etc, those comments make him ignorant of what happened on that rig. For sure there were engineers, medics, pilots, hydrologists, drillers, cooks, office workers, janitors, etc etc etc that worked on that rig. And regardless of the workers' social status, job title, recidivism rate or whatever, 11 of them died. 15 kids lost a parent. So whatever, the guy made some remarks that might have been relevant to the technical side of things. But to slag the workers that were caught in an unfortunate situation out of their control, yeah, he's an asshole for saying that.
