Thank you for posting. This story can't be over exposed. I spent my college days in Boulder and it was similar to this when the Rocky Mountain Peace and Justice Center organized traffic-blocking street demonstrations against nuclear weapons, nuclear power, pesticides, or any number of other things that have never produced the "child poisoning" these, ahem, 'science awareness advocates' then foretold. But this is worse. Perhaps they are emboldened by the growing acceptance of the tactics of al Qaeda, or the Weather Underground.
Yes, I was wondering when Caldera's fond remembrance of Kumbaya peaceful discussion days occurred. I did not show up until 1988 -- the civility was long gone by then.
