Re: Bias in, bias out
Well if 'your' IP address gets blocked because someone else on the same ISP is spamming in you might be moderately grumpy. You might get the feeling that the authorities aren't on your side. You might think that as you are 'guilty' in the eyes of the law you may as well do something criminal.
At least in the UK our police generally stop and search, rather than US style shoot and search.
