How is money laundering detected and proven?

If a bar has sales of $2000 a night, they can easily launder almost that amount. Just pad some receipts and markup some wines.

Its when the have sales of $100 a night, once every 6 months and yet claim that they had sales of $10,000 that they have a problem.

Yesbut this really isnt the best way as you then have to pay all sorts of taxes on the income. Crooks dont like paying taxes.
