Out of curiosity, for those of you who believe true justice was not served, can you address any of the following:
Where was the failure? (evidence, laws, jury, judge, prosecution, defense, ... ?)
Is there something we can change about our laws, legal process, or elsewhere that might prevent this injustice from occurring again, either by preventing the crime in the first place, or by getting the right verdict next time?
If you choose to say, "get rid of racism" or something non-actionable, then I'll agree, generally, but I'm thinking more in terms of actions we can take that are useful and practical, rather than "world peace" wishes.
