And this is what kills me when it comes to educating my kids about how police are aloud to behave in the US. "Law enforcement" means you are enforcing the law. You can't enforce the law if you don't know what it is.

"Oh. I thought the speed limit for that section of road was 25mph. I thought it was a bit odd everyone was going 20 over, but... Oh well! Lucky me!"

"I thought it was illegal for a black man to walk around town in a red hoody. So, arrested him for possession of meth, even though he had nothing on him. Oh. He's also dead because I accidently shot him four times in the back with what I thought was my taser while he was handcuffed and in my car."

SCOTUS: Yup. Seems legit.
