In his Times column, Philp claimed that "two-tier policing" actually exists.
His evidence was that another murderer wasn't sectioned under the Mental Health Act because he was black, and because of the over representation of black males who are sectioned. Along with a quote about how the Southport killer's former head teacher was accused of racial stereotyping.
Neither of his examples actually involve the police. They would be the remit of mental health services and the education system.
