Obviously satire. I think most anarchist agree that cops are part of the working class. They are infested with terrible people, due to the structure of their organization and it's relation to the state. As an anarchist, I'd postulate that groups like the police are useful in some aspects. Trained to respond to emergency situations and violence. Quick response (depending on the area's wealth...), well-versed in rights and freedoms (ideally...). They should be organized democratically at a grassroots level, represent the community, and work toward empowering the community rather than enforcing bullshit laws.
Law enforcement is not a part of the working class. Law enforcement actually represents a very distinct class that does not fall easily into the capitalist/worker paradigm. They are guaranteed economic security, due to state privilege, state employment, police unions and pensions. They are also given special legal status that gives them privilege in respect to acting violently. They don't own the means of production. They do, however, own the means of enforcement on claims of capital. That is a product or service that they have a full monopoly on. And they use it primarily to protect the elite, the state and the individuals at the top of the hierarchy.
The relation of an organisation to the state defines whether it is working class or not, and the police exist to suppress the consciousness of the working class. They terrorise minorities and infiltrate leftist groups. Any "anarchist" who supports the police is likely a middle class white man that has never been in close contact with them.
Neither do clergymen. I suppose the priest is the natural ally of the socialist?
