Year - 1984
Place - India (most populous Democracy in the world), two cold-blooded tragedies within a month in winters of 1984 killed thousands, overshadowed the seasonal celebrations & ceased all the celebrations of coming generations. Millions of people suffered...suffering, awaiting justice.
These events shook the world. Responsible-Guilty people/criminals just shook their head (left to right) saying "No! Not Guilty" & this mixed with money & few formalities proved their innocence. Indian Polity, system remained silent. At least, a pre-recorded voice by Indian Railways often says "Inconvenience caused is deeply regretted."
