It won't. Corruption in public office has been going on for centuries, and often on a far bigger scale than this.
It's time people stopped foaming at the mouth every time a human failing is publicised, and started getting a sense of perspective. MPs - like all of us - are human beings, and from time to time their failings will come to light. I am sure there are doctors,dentists,solicitors, police officers, accountants, and people in positions of trust all over the land who regularly cross the line. They get caught out, and are dealt with, usually without it getting into the papers.
MPs are a high-profile bunch, so their peccadilloes make juicy grist for the red-top mill.
'Minor fault or sin' when £13,000 is ' bogus expense claims'. To me it is fraud especially with a highly educated person involved and can't even claim ignorance. He's a thief and should serve his term of imprisonment fully although I do sympathise with his family troubles and losses. We all know he won't serve anywhere near the full term but at least I can't be sued calling him a thief.
Just been reading today about a health service manager whose yearly salary was £35.000, who committed fraud to the tune of £43.548 over an 18 month period from the NHS. No previous convictions and unblemished previous record, he's just got 18 months for his crime.
What is the difference between using a ' fraudulent way' to claim money and thieving? Whether or not the money was 'due' should have no baring on the way the money was 'got'. As I previously said, he's educated and should know right from wrong and he took the wrong way and was found out and found guilty. He's a thief and will, no doubt, run a shorter spate in prison because of his social status. If it had been me I'd have got a lot longer and even being let out for 'good behaviour' would still be longer than the sentence imposed on Mr MacShane.
