The crime must still be proven and people in Oklahoma still have common sense, even those that sit on juries, so I have faith in the people of Oklahoma to make sure this law is administered correctly.
There will always be straw arguments against any and all laws, especially those that have a moral overtone. The left loves to play that game. (Not that I am accusing you of being a lefty, just a side note.)
Not a straw argument, but a real question: with the passage of this law, why shouldn't a child molestor kill his victim?
He's already earned the death penalty, eliminating the witness can't hurt him any more and leaving the witness alive can only harm him.
That's why I have a problem with this law. It's about emotion over reason. It claims to protect children, but could well do the opposite.
I know it's hard to keep a clear head when considering crimes against children, but we must not let our emotions override our good judgment.
