Do all currency serial #'s get randomly spot-checked , in normal-routine-circulation ? If so, I wasn't aware of that.
In other words: When investigators want to go check individual bundles of $$, then Sure: They compare #'s. But does the entire country's money supply have serial #'s checked, at some given check/choke point of the circulation system ?
Example: When you spend $20 at 7-11 for a slurpee, no one's checking the serial #, right ? And when that 7-11 takes their nightly deposit to the bank, no one at that bank is checking the serial # to see if it's connected to DB cooper, right ? And so forth through the circulation system.
It would have to be a concerted / purposed check, d/t some individual suspicion, right ?
Unless I'm wrong, and that in modern digital computerized times that we live in, that the currency supply is somehow going through a banking system "choke point", where currency serial #'s are being scanned perpetually, by some sort of computer reading system.
