Why did the police spend so much time chasing petty criminals when all the top gangsters were senior bankers?

They are now just about to grab a few million pounds off the counter on their way out. Bye bye people, sorry for the mess but we're just taking a few million each to tide ourselves over until the next scam. Thanks to you tax paying suckers, we use the legal tax avoidance loop holes so our little 'bonus' will be tax free. I guess you are all feeling like real chumps by now. Well cheer up at least we will be enjoying ourselves down the South of France.
