All you need if 500,000 people on a daily basis at 9AM...walk in and ask for $5,001 in cash. Walk around for six hours, then insert the $5,001 in cash back into the bank account. It’d take a month for the Feds to wise up that they were wasting six million reports a week on this banking report deal.
No, they will never consider it a waste, just something to spend more on. Look at how the supposedly innocuous and unobtrusive firearms registry in Canada mushroomed into a multi-billion dollar debacle. There are still Canadian gov't bureaucrats who are sure if they just threw more money at it the whole thing would have worked out positively.
