8/21 the unsolved mystery

It has been 2 years since the grenade attacks on the Awami League leaders, including chief Sheikh Hasina, which left numerous dead and hundreds of persons crippled. 'Who was behind it?' the question remains unanswered till today. What should be the peoples' role now instead of just mourning the deaths? Politicization of the investigation process is one of the biggest failures of this government.
