The calls from police and various former politicians for drug policy reform will no doubt sink as deep as the money wasted year in and year out on the unsuccessful war on drugs -- partly out of fear of being soft on law-and-order issues and partly because politicians are keen believers in the sunk cost fallacy.

The drugs war is a prime example of something that politicians and some corporate leaders do all the time -- get caught up the sunk cost fallacy, which might be colloquially designed as sending good money after bad.
