Then you are wrong.
The mugger can be tried and convicted because he does not have the authority. No one from the government will be tried and convicted for enforcing the law as it is on the books. They have the authority.
Your logic fails, and I am done.
Irrelevant. That an illegal law is passed in no way conveys any authority to enforce that law.
Again, ability to enforce does not translate into authority to enforce.
Ability to try and convict does not translate into legal authority to do so.
In Hitlers Germany it was quite legal to commit mass murder. And the ability to do so existed.
Though Hitler hardly had authority to do so.
You logic fails.
Your done.
