I really don't think there is a racist agenda to execute minorities mochafish. Sorry.

I also believe that the US and the UK system (which are very similar) are the best available options.

I do not think that France's guilty until proven innocent is a credible alternative (although perhaps some of their aspects such as the panel of judges rather than jury has it's benefits)

Of course any legal system is going to have loopholes and I think that the current situation where the bias is towards innocence is the right one.
