**The death penalty would be a stronger deterrent if a man knew that he would be dead within a year**
In the past, Presidential assassins met their deaths within two months of the crime. It still should be the same.
Ecclesiastes 8:11-13
King James Version
11 Because sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set in them to do evil.
They sure couldn’t wait to execute McVeigh, did they?
