There is something important here: St. George Police Department officially uses automated license-plate readers (ALPRs). Its policy says the system automatically detects plates and can be used to identify stolen/wanted vehicles, stolen plates, missing persons, active warrants, and for “suspect interdiction” and electronic surveillance.

So if you personally experienced a St. George officer notice your California plate and then follow you for three blocks, it is reasonable to consider the possibility that the plate attracted attention. That still doesn't tell us why the officer followed you—the plate could have triggered an automated alert, or the officer could simply have decided to take a closer look.

The ad for las Vegas, "What happens in vegas, stays in Vegas."  No it doesn't.  It can stick to you like stink and never leave you.

Reacted ❤️ to “I'm convinced that "community policing" is a constellation of forces that put direct but unseen pressure on citizen. 1) electronic surveillance, like traffic tickets and a general panopticon surveillance of all activity to secure courtroom evidence, 2) word of mouth from any and all citizen in the city organized a la Stasi as in "Lives of Others," 3) squad cars cruise the blvd to get real-time compliance, muscle the occasional vagabond, or answer complaints called into the PD, 4) City Council, 5) Zoning, Chamber of Commerce, & grocery chain surveillance under the guise of "theft protection."  Did I miss anything?”
