Richard,
I always suspected you were a fake libertarian. Today you give us proof beyond any doubt. Your knee jerk defense of EVERYTHING this authoritarian Trump does, gives you away. 

Arpaio violated people's constitutional rights. He arrested American citizens and held them until they could prove their citizenship, based on nothing but their looks (if you're brown, you're going down). He jailed journalists for writing unfavorable stories about him. How does someone like you, who fancies himself as a libertarian, support that?

The president can’t use the pardon power to immunize lawless officials from consequences for violating people’s constitutional rights. 

If you celebrate or ignore that step from this president, you will have to celebrate or ignore it from every president who follows him, and I sincerely doubt that’s what anyone who calls themselves a libertarian would truly want that, unless they were really an authoritarian masquerading as a libertarian, which you are.
