Understanding Blood Guilt

Wouldn't it be wonderful if our president said this about abortion? Wouldn't it be wonderful if even the Church made such a principled stand?

Understanding Blood Guilt
From Mike Warren:

The following is copied from a wanted poster that was distributed by Secretary of War Stanton following the assassination of President Abraham Lincoln. It shows how far we have fallen from a biblical world view that once influenced our nation and protected our liberties.

War Department, Washington, April 20, 1865
$100,000 REWARD
THE MURDERER
Of our late beloved President, Abraham Lincoln is still at large...

Let the stain of innocent blood be removed from the land by the arrest and punishment of the murderers. All good citizens are exhorted to aid public justice on this occasion. Every man should consider his own conscience charged with this solemn duty, and rest neither night nor day until it be accomplished.

Edwin M. Stanton, Secretary of War
