It’s not. Police Departments are bastions of (low grade) White Supremacy, prep schools are bastions of (high post) White Supremacy.
Police are heavily indoctrinated into believing they are the primary beneficiaries of white supremacy…they’re not. They are the garbage men of white supremacy, meanwhile those at the prep school grow up to really pull the strings of it.
But they have brainwashed these cops (and those who look and act like them) quite profoundly. It’s gonna be difficult to breakdown all that brainwashing the “former cop” described above.
