Good question. The police can’t be everywhere.
They don't need to be. The phone number for reporting (squealing) on you by your neighbors is sufficient evidence for LE to show up at your door an threaten you. Don't doubt me on that. Your assh*le leftist neighbor will take a picture of you and the police/judge will rule that is sufficient evidence to fine you. No jury of your peers required.
The Nazis and their collaborators would have positively creamed over cell phone cameras.
And will the police in that county bother to enforce it?
