Having a bored and well-funded cop on every street corner, looking for crimes, is not the best thing for a free society. "Make sure everyone pays their fair share" seems reasonable, but all too often degenerates into "spend years harassing a single mother over the EITC tax credit, then chalk it up as a win when she folds."

I've seen those return-on-investment studies saying "for every $1 allocated to the IRS, they collect $10 in unpaid taxes," but how much of that comes from harassing people who end up paying because they can't afford to spend years litigating in tax court, versus people who were actually hiding income?
