When system fails, there is a danger that people may be more likely to take things into their own hands. It's historical human nature and a truism, doesn't make it right, just a natural by-product of failed justice. That's why it's so important to construct legal systems which make it probable that the innocent will be kept out of jail and that the guilty will be kept in. We should have expectations regarding our fellow citizens. For example, we should expect that parents should report the accidental death and/or kidnappings of their children with haste and co-operate with the authorities to save children who need to be buried or rescued. We certainly should be able to draw assumptions and hold them accountable if they don't. We should expect that our fellow citizens on juries should actually read the judge's instructions and be able to convict a woman who murdered her child without needing to see a video of her doing it. We should expect that lawyers don't lie about innocent witness to save guilty clients. People who terrorize other should be caught accountable by the system, although we have just seen examples of how our system often fails in that regard.
