IMO....I see that as the same situation, he canned the police and replaced them with the "Brown Shirts"... his own people as you say. These folks today that want to defund police will want the void filled with what, do you think?
Not really the same though as HItler didn't get rid of the police force at all. Hitler purposefully filled empty positions with people who would carry out his laws more easily (honestly similar to how we do things with the War on Drugs in some places). These folks want to get rid of police completely and replace them with the community just watching out for itself. Completely opposite position.
