Phil, You make a good point about judicial rulings changing. You're right. I agree. But until the next court says differently, in the meantime, the rule of law means that law enforcement obeys the courts. I assume you'd agree with that. 

What you're missing, I think, is that more than 1 million US citizens in that county are hispanic. Arpaio's rule equated hispanic with illegal. He treated our fellow citizens as if they were illegal, simply because their features were hispanic. That's what the court ruled unconstitutional. I hope you don't approve of discriminating against citizens for looking like immigrants. Because that's what he did. That is not "doing his job." And it's not patriotic.
