Billions of dollars are wasted each year trying to prevent ‘dirty money’ entering a financial system that is already awash with it. The authors challenge the global approach, arguing that complacency, self-interest and misunderstanding have now created long-standing absurdities.International and government policy makers inadvertently facilitate tax evasion, corruption, environmental and organised crime by separating crime from its root cause. The handful of crime-fighters that do exist are starved of resources whilst an army of compliance box-tickers are prevented from truly helping. The authors provide a toolbox of evidence-based solutions to help the frontline tackle financial crime.
