text: The likeliest explanation for all this is that OSTP's Polar Vortex video was originally produced and posted not as the personal opinion of the agency's director, but as an agency project. OSTP sought, and succeeded, in getting widespread news coverage for the film. But once its inaccuracy became clear, the agency invoked the personal opinion excuse as a way of avoiding accountability, and it did its best to maintain that fa ade even if it meant going through time-consuming and expensive litigation.
