Yes, kind of. Surprise, crime happens. HSBC laundered what, $670 billion dollars of Mexican cartels? How many executives ended up in prison? Didn't they pay some tiny fine and that's it?
Also mixing is not laundering. Mixing only allows you to stop the tracing. Converting these mixed coins on a large scale to something like dollars is very very hard. Most exchanges that interact with the traditional banking system do check where you got the money from. It's not like you can send $1M worth of tumbled coins to Bitstamp/Kraken/Coinbase and convert them to dollars without tons of paperwork. And it's not like you can buy a house/car/boat with these coins and expect the IRS not to show up.
