You're right. However, the word "slaying" doesn't have the same impact the word murder does in the average person's consciousness. It's liberal brainwashing at its finest.
When Average Joe, sitting in his recliner with his ice-cold beer and the remote in his hand, hears the word "murder" he pays a little more attention than if he hears the word "slaying." My guess is that the pro-aborts are seeing how all that coverage is backfiring on their hero, so they are backpeddling to win the war in words.
From what I can tell, Average Joe is not sympathetic to George Tiller. In his heart, he's thinking the guy got what was coming to him and changes the channel.
I see where you're going with this. But the media is up in arms over this killing yet nothing is being said about the murder at the recruiting office. It's hard for me to see the media backing off on verbiage yet going all out to condemn the act. No, I think this is merely one journalist's choice of words.
