Just because the undercover said " I want to use the BTCitcoins to purchase stolen credit cards" the seller of the BTCitcoin did not care and still sold the coins.
Makes them complicit in the illegal activity of "money laundering."
That is correct. But what if the cop would not have asked this? Just bought 1 BTC and $30K the next day? Does anyone here seriously think that would have been it?
Even if the guy would have said, $30K is above the $10K money laundering limit, that would not have helped, these cops were looking for an easy success instead of doing some real police work, catching some real scammers.
It is easy to reject a buyer who openly says he is doing something illegal; actually that would get you in trouble in almost every country. The $10K money laundering limit is also not the problem.
The really nasty part about this case is that, obviously, everyone who sells anything for more than $300 in Florida for cash, commits a felony? Was that law copied from North Korea? Is that not against the constitution, to prohibit private citizens from selling their personal property (such as gold, silver, foreign currency that may be left over from a vacation, or BTC) for legal tender?
If Adolf had won the war, it couldn't be worse.
