Blue: The New Black...or Pink.
Not true. Police are not a protected class. Although they might think they are. Homosexuals may be depending on where you are. Blacks definitely are.
A business can freely discriminate against accountants, attorneys, police, nurses or piano players if they so choose. Not a smart thing in my book, but its legal.
