This is the situation you get when solicitors make the laws. Too wrapped up in their ivory towers to notice or in some cases even care that they are shafting the country just so that they can keep a steady flow of cases to maintain their lifestyle.
The laws should be made by the people who have been affected by crime, with advice coming from the solicitors. Then you would see a true fall in crime, not this massaging of the figures to make it look like the system works.
