Whereas I can appreciate the need to apprehend and stop legitimately criminal activity... some of these methods are just too damn invasive. I'm not typically someone who runs around in a circle squawking about "my rights, my rights, my rights!" but this sounds like it was more based on someone's idea "in theory" than anything substantial.
Or maybe they were also hoping to catch anyone trying to cheat the IRS by running a cash business?
I can apprec legitimate police work as well, which is why this sort of nonsense just irritates 😂
