On Saturday, California State University Los Angeles Professor Melina Abdullah tweeted out a clarion call to Americans: stop calling the police on black people.
Now perhaps she meant that you shouldn’t call the police on somebody just because they’re black — which, of course, is correct. You shouldn’t call the police on somebody based on an immutable characteristic, rather than based on criminal behavior. That’s racism.
But then she clarified: you should never call the police.
