As a country we should be ashamed at the idea of nurses and policemen and teaching assistants having to go to food banks, not be questioning them.
I think we might have to accept that there is, and always has been, broadly speaking, two diametrically opposed views on issues like this. There are those who are deeply suspicious of anyone who is getting any sort of benefit or handout because they might not be deserving of it, and those who feel it is best to believe people are in real need and who are prepared to accept that a few cheats might get through the system but it is more important to help all people in need than worry about possible 'cheats'.
