Ex_Mil8 saidIt is unfortunate that a few innocents have been caught up in these seizures, but you can bet the vast majority of the cash seized under this program has been the proceeds of criminal activity (or, at the very least, tax evasion). Most people conducting legitimate large cash transactions will do so by bank transfer. Not only is it safer, but it prevents awkward questions when the police find $75k on your back seat during a traffic stop.
While I don't disagree with that, for me it is more than just a few innocents; rather, I associate a way of life, a history of legal tender, a tradition of innocence until proven guilty, a guarantee of presumed freedoms which such action seems to attack fundamentally. Never mind outright seizure, I'd probably have issues even if such "evidence" put the person on a watch list to look for actual future crime.
Insisting people don't keep their cash in a mattress says that there's something criminal about not trusting banksters.
So even if the action turns out by chance--however good that chance might be--to be correct in the ends, if not in means, you wind up with corruption all around.
