What is borderline racist about it? It's absolutely true. African-American parents and grandparents have far more to be worried about when it comes to mistreatment by law enforcement

She's exactly right. Charlotte and Aidan Clinton-Mezvinsky will not face the fear of mistreatment by law enforcement that many African-American children face
So it roughly translates to: "because my grandchildren are white, they will get in less trouble with the law." Congrats, Clinton, you've just created a new Trump atrack: "Crooked Hillary Clinton is so racist that at a black church she actually said "because my grandchildren are white, they will get in less trouble with the law." She is saying that Blacks are criminals! Vote for me, what do you have to lose ?!?
And unlike what you think it's true and she wants to actually change it.
