The implied suggestion in your post is that we should accept people going through the situation that the man in the article went through in order to make it harder for criminals to commit benefits fraud. That is, quite frankly, an utterly inhumane reaction to the problem. Innocent people in dire situations are far more important than protecting a (relatively small) amount of money being paid out to criminals.

We do need to try and catch criminals where possible, but if the cost of catching them is innocent people suffering then we should do less to catch them and just accept the cost instead.
