The toughest sheriff in America is dropping hints that he would like a pardon from the President. Former Sheriff Joe Arpaio told the Arizona Republic that he would accept a pardon from Pres. Trump. See Politico news report here. I recently wrote about the court finding him guilty of contempt here. He says he talks with the President now and then, but will not brag about it.
So, he does have some self-restraint, after all.
