The law never had anything to do with it. It’s only that, from the perspective of white nationalists, generally cops are on our team. If it’s a criminal on our team vs law enforcement on their team, they’ll go full-on “fuck the police” without an instant of hesitation.
I have seen this for years in the meth head community. Whether or not they’re saying “fuck the police” depends entirely on who the cops are currently arresting. Competing meth dealer? Fuck yeah, they’re doing their job! One of their own? Fuck the police! A Mexican? Fuck yeah, thin blue line!
I’ve actually seen someone go from support to hate and back to support in the space of a single conversation.
