Not federal judges.
... and so are legislators, this isn't about cops.
The point is, people who stand for election are subject to political forces that other people aren't. That why we don't elect judges, at the federal level. That's why our politicians don't give orders to law enforcement agencies that they administrate. A person who stands for election has no higher priority than putting on the kind of show their voters want, and that doesn't necessarily mean they follow the law. Trey Gowdy might have been a perfectly good prosecutor, but when he ran for Congress, he stopped focusing on the law and instead focused on his voters. And his voters are crazy.
They decide "how to enforce the law" and you are the one who used the term law enforcement. So basically, laws ARE decided by voters and elections.
I'm all for that. What I'm not in favor of is politicized justice.
The President appoints the top law enforcement officer as well.
Yes. Usually, the person chosen is a legal rather than a political figure. Unless I'm mistaken, Sessions was the first AG picked from Congress during my lifetime, and the first with a background in electoral politics in a very long time. Of course, the President can name anyone he wants, but a good AG shouldn't be a politician, and shouldn't bring a huge agenda of their own.
Imagine if a few "law enforcement" officers decided to take the law into their own hands and quote "save the country. I can do that on many levels" and " we need a plan B" or "We need an insurance policy to stop Trump from being President" and these law dogs happen to be leading very political investigations.
The way the Justice Department is structured, investigations are intended to be initiated from the bottom up rather than the top down, to avoid it becoming politicized. That's a convention that administrations of both parties have stuck to for decades, with the most notable departure prior to this year being Nixon.
Mueller is a slack jawed lackey and Trump is the Commander.
Mueller's a better, fairer man than you, me, or Trump will ever be. He deserves respect. He deserves the space to get his job done.
