Does everyone who says "abortion=murder" have dr. tiller's blood on their hands?

When the Bible says: "You must not murder", it isn't just talking about abortion. Murdering human life at any stage is wrong. I am fully against abortion, but killing that doctor isn't the answer. He has God to answer to, not other humans. Saying something is wrong, and that God says it's wrong doesn't make you bloodguilty if something happens. If I were making violent comments advocating his murder, then yes, I'd be partially responsible.
