By the way, you've now claimed that
a) 99% of all cases at a magistrates court were benefit fraud cases
b) you believe this to be the same in any major town across the country.
Which rather begs the question how the shoplifting, burglary, speeding, parking, assault and, well all the other stuff dealt with by magistrates gets done.
So I went and looked this up - you know, that research thing you claim to do. Here's the Ministry of Justice statistics page. Fig. 2 shows that around 30% of magistrates court business is summary motoring offences.
Further, down right had side, you will see a downloadable spreadsheet of national statistics called "Offences tables - September 2011". (Haven't spent enough time to understand if this is magistrates courts only - that's something you could do, seeing as how it's important for your job.)
The offences for the 12 months ending September 2011 are as follows:
Violence against the person - - - 58.3 thousand
Sexual offences - - - - - - - - - - 19.7 thousand
Burglary - - - - - - - - - - - - - - - 32.0 thousand
Robbery - - - - - - - - - - - - - - - 12.5 thousand
Theft and handling stolen goods - 176.5 thousand
Fraud and forgery - - - - - - - - - 49.8 thousand
Criminal damage - - - - - - - - - - 10.9 thousand
Drug offences - - - - - - - - - - - - 96.1 thousand
Other indictable offences - - - - - 116.2 thousand
Indictable motoring offences - - - 4.1 thousand
Summary non-motoring offences - 602.3 thousand
Summary motoring offences - - - 654.6 thousand
Even if benefit fraud were all of the fraud and forgery cases, the absolute maximum would be 2.7 % of all cases.
