On historical perspective

I'll give Roland Priddle this much: he's absolutely right in his impression that the best way to argue for waving through expanded tar sands pipelines without an unbiased review is to pretend that nobody has learned anything about environmental protection, oil or dilbit spills, climate change, or energy industry trends over the past six-plus decades.

But I'll suggest that the public interest is probably best served by analysis based in the present rather than 1951.
