Imagine they were treated as the thugs they are…

Can I see your ID and warrant please?
You don’t wanna show?
Then get off that person!
You don’t?
Here’s your kick to the face then!

edit: remember to cover your face and head like those thugs do before you kick their faces. Make sure they can’t come after you, so don’t hold back.
While you’d be right to defend an attacked person, you wouldn’t want to end up in this joke of “justice system”.
