Well it's called justice, and the decision to charge must be based on evidence, therefore it's correct to have the charges tried in a court of law. If those charged are found guilty and sentenced, then justice will be seen to be done, it's only fair to those who died or injured and also to their families and friends. It's not that anyone wants to be vindictive, but if a grievous wrong was committed then those who committed it mustn't expect to evade the consequences of their actions.
What I want to see also delivered is charges against those in the political domain who conspired to cover up and lie consistently while laying the blame on the victims while excusing the perpetrators of that dreadful event, however as always I feel I'll be a long time waiting for that.
