The problem is the system was originally intended for a nation of honest people.
Unfortunately there are a lot of thieves out there.
It doesn't matter whether it's benefit fraud, expense abuse, tax fraud, shoplifting or bank robbery. It's all theft that ultimately costs those amongst us who are honest.
We've all witnessed successive Governments introducing schemes to catch out the wrong uns but it's never resourced properly. It serves the purpose for what it's intended - a political point scoring exercise. A wee massage of the figures here and there and they can even show that such schemes have been successfull..... I think we all know differently
