Common Law is better than codified law. That's the only reason we have juries and don't just let judges decide the fate of the accused. Can you imagine, in this country, judges the sole decider of your case?
The reason that the UK and US have had such cuntish law enforcement is not because of english common law. It should be noted the UK cancelled some of common law's basic tenants, like the right to a jury trial, not only afforded to indictable offenses, any crime with less than 3 years imprisonment is decided by their famously haughty aristocratic judges now.
