Should MPs and MSPs Be More Accountable

I was shocked and Horrified to watch this pragram last night Thursday 11 October 2007 and find that MSPs And MPs cannot be charged with telling Lies.
Clearly they have a duty to the Electorate to express any concerns they have.
Clearly they are employees of the Electorate.
How come then people like Ed Milne etc are finding it extremely difficult to find MSPs to represent their interests.
How come people like Ed a 69 year old pensioner is being Ignored by his local MSP?
The sad case of Ed can be found here:

I done some articles on MSPs on the BBC web a while back and they can be found at the following:
