CNN's Kate Bolduan had former Education Secretary Arne Duncan on her show to discuss...well, vapid ridiculousness. The absurd and vile practice of giving airtime to the killer's dad so that he can praise his son as a good boy, and make excuses for his son murdering 10, wounding 13, and taunting them while he was in the middle of terrorizing them, is so unconscionable it should defy the ethics of any journalist with a heart. But no.
