How is it possible?

It's obvious that the role of the government before August 17 was quite questionable. Most of the newspapers in Bangladesh published the news of the potential threat of Islamic militancy. They gave the facts and details. They relentlessly tried to pursue the government to take action against militancy, but they failed. At that time the government said that the Islamic militancy was a déjà vu created by the media. They also withdrew the Time Magazine from the newsstands because they published a feature about the potential threat of militancy. If they took necessary steps at that time, some innocent people might have escaped death.
After all, it's Bangladesh, where nothing is impossible. Farmers demand electricity but receive bullets. Law enforcers kill people without trial. Strange!
