U.K. Law is very oppressive... which is why our fore fathers revolted.... and took this country for their own.....

2 years probation for a diving knife locked in a car is nutts.... How bout the kitchen knife in your drawer ??? that's a concealed weapon.... you could go to prison for life... hope they don't find that....
if you got enough money to be able to afford a car over there in the first place.... that means you have a decent job... and a good work ethic... which also means you're re a responsible citizen.... doing exactly what you said you were... but if they let you off.... they can't grind you under... and make you obey....
