There's a GunTuber I enjoy watching (he's way more libertarian than most of the others), "The Yankee Marshal" who called the police "government's first line of defense".
I would say he was slightly wrong on that point.
Police are the government’s first line of offense. The government’s loyal aggressors.
If they were truly defensive I wouldn't despise them.
Since I have no intention of aggressing against any government employee, cops would never have any reason to interact with me. That's not what they do. Police seek out people who would be perfectly happy ignoring government, and proceed to zealously violate their natural human right to ignore government.
That's offense, not defense. It is archation.
This is why there are no “good cops”.
