It is true. There are 100's (probably 1000's) of confirmed news stories by now. Just like people get into car accidents is real, even if you personally haven't been in a car accident yet. And people dying is real, even if you are still alive.

You are a sample of '1' and you don't get to invalidate other people's experiences based on your own. The only reason you do not notice, given that it is true is because you would either rather have it not be true or because you are actively working not to notice.

Nobody is being grabbed off the street for “being brown.”
