The original last sentence in this letter to the Boulder Daily Camera said this:
"If the oil and gas industry puts fracking wells in our neighborhoods, threatening our lives and our children's lives, then don't we have a moral responsibility to blow up wells and eliminate fracking and workers?"
This is NOT protected by the First Amendment. I'm not saying that the idiot letter writer should be charged with a crime, but the Daily Camera crossed some lines here, and the ridiculous excuse by Opinion Editor Dave Krieger doesn't cut it: http://www.dailycamera.com/columnists/ci_30938193/dave-krieger-editing-fracking-and-civil-disobedience
