United in Horror - NYTimes.com: "It’s possible that Jared Lee Loughner, the young man behind Saturday’s rampage in Tucson, will have a more direct connection to partisan politics than an earlier generation’s gunmen did. Indeed, many observers seem to be taking a kind of comfort from that possibility: there’s been a rush to declare this tragedy a teachable moment — an opportunity for people to cool their rhetoric, abandon their anger, and renounce the kind of martial imagery that inspired Sarah Palin’s PAC to place a target over Gabrielle Giffords’s district just months before Loughner gunned down the Arizona congresswoman."

I highlight this for its use of "teachable moment." Doesn't "teachable" describe the moment--as in the moment is able to "learn or be taught." Shouldn't it be "teaching moment" instead? I hate this phrase.
