How's it fair,when it clearly 'aint OK??

We are all by know sick of hearing about the MPs and their expenses...claiming anything from Kit Kat's, toilet seats and dirty movies to even more essential items like swimming pools and massage chairs. On and on this has rolled on, with thousands upon thousands of pounds of our money gone to waste , with no police investigation, it seems life as a politician has it's perks.

A woman in Staffordshire has been claiming as a single parent, who's living alone and unemployed. In fact she is working, lives with her partner. It turns out she has managed to get over £50.000.

Of course this is wrong, but why has this woman been charged, had a fine and is now facing a jail term and our politicians are getting away with basically the same?
