I feel very strongly about it. It doesn’t mean we can’t be more diligent in ensuring that only the guilty are punished.
But murder must be punished.
I don’t know how diligent we should be. Or whether capital punishment is the appropriate punishment. However, whatever we decide, it should be administered.
We train dogs by using clear, consistent commands. Good parents have rules for their kids. They don’t let the kids play one against the other. We should be just as consistent with lawbreakers.
