Look at every executive agency at the state and local level. Park Districts have their own police forces. It is an unprecedented amount of police force and unnecessary.
There’s an additional element that isn’t mentioned. So many agencies now rely on Administrative Law which is a “judicial” branch of the executive office. By having their own police force there is no check or balance on proper service or enforcement.
In not having to rely on a local sheriff or municipal police force you lose a check on overreach. Not to mention that in America the judicial and executive branches are to be separate as insurance of individual liberty. The concept of Administrative Law was to unclog the court system. Instead it’s simply allowed governments to run roughshod over individual rights and generate revenue through fines.
Because of our anti-American education system, I wager not five in a hundred even understand, let alone agree with what you are talking about.
Government need not fear and defend itself against a free people. Only an oppressed, beaten, fearful, . . . people pose any threat.
