Yeah if you're poor and vulnerable you're screwed anywhere in the capitalist world. But in the states you're screwed even if you are middle class (absurd bails) and have a good lawyer, because the government is so over its head that they will jail you with fabricated evidence and then give you no chance of justice.
True, the UK is not much better than the US. But otherwise many countries in Europe are incomparably safer. If not because of more reasonable justice systems, just because people are more laid back and sane here than in the states.
