As someone who works at a financial institution, it's news generally because money laundering activity tends to be highly profitable for banks, since they get to collect fees on those transactions. There are almost no incentives for us to flag transactions on our own (unless we're being super humanitarian) without legislation/regulation, because as long as they get their money there's no downside except for victims of the crimes that the money originally originated from.
At least in my opinion, the legislation and big-deal-making is merited in cases like this, for the benefit of society.
