The news is yet another evidence of our failing judicial system which fails to provide justice even if the evidence against a criminal is abundant. We can't blame the judiciary alone. It actually involves the whole system starting from Police as investigators, the Prosecutors, the Witnesses, the Lawers, the Judiciary and finally the Executive. It also includes the Legislative which fails to make necessary laws.
In short, it's our failure as a nation that criminals don't get punished and take the Law for granted.
