Anyway I note that a misspent youth of getting into minor legal trouble and tax-dodging can actually be beneficial, in that you learn how these agencies actually work and what constitutes a legitimate government action. Is it on paper? Was it (preferably) served to you at the front door by a uniformed deputy?
What is the difficulty/cost/risk level of making a phone call anywhere in the world vs. outfitting someone in a convincing-looking police uniform of that area? Type of thing. I know I'm preaching to the choir...
Maybe if I get one of these calls I'll tell them "Just go ahead and send a deputy like usual." Except no, because if they're especially spiteful they might S.W.A.T. me.
