Rwandan Genocide.

"The Rwandan Genocide was a genocidal mass slaughter that took place in 1994 in the East African state of Rwanda. Over the course of approximately 100 days (from the assassination of JuvĂ©nal Habyarimana and Cyprien Ntaryamira on April 6 through mid-July) over 500,000 people were killed, according to a Human Rights Watch estimate.[2] Estimates of the death toll have ranged from 500,000–1,000,000,[1] or as much as 20% of the country's total population. It was the culmination of longstanding ethnic competition and tensions between the minority Tutsi, who had controlled power for centuries, and the majority Hutu peoples, who had come to power in the rebellion of 1959–62 -Extracted from "Wikipedia, the free encyclopedia."

The picture you see above tells its own
Tales, death really happened. Why it
Happened... Even I am truly perplexed;
Why so hard the end result - why over
One million people had to die; in 100
Days, 20% of the countries population
Perished; just imagine if 200 days had
Been allotted to the killers. Many killers still
Walk freely... Many still remember the kill;
Like animals age but still retain their
Killing instincts; I wonder if some not
Lust one more 100 day killing spree; to
Somewhat finish the job.
