I'm mad that I had to sit thru "41 Shots." 
actually, there's some nice lines in there too. To my ears, it wasn't all pile on the police on that one. The "is it a gun, is it knife, ..." is from the perspective of the officer and how he has to make a quick decision that can have consequences. Now, does he end up making the wrong decision because of the skin of the victim? That's the suggestion, but the passage conveys that it isn't easy in the police's shoes.
Also, Lena talking to her son offers up some advice that I think is right -
"Promise me if an officer stops you'll always be polite
Never ever run away and promise mama you'll keep your hands in sight"
I say I'm completely on board with that and you'd have a lot fewer incidents if everyone did this. That goes for all police / public interactions. Try to make it easy for the police and let him/her do the job. It is a fraught situation, and, maybe I'm all wet, but I think there's some empathy across the board on that song. however, I'll acknowledge that he started writing it to protest what happened.
