Faisal Arefin Dipon, was killed, and two writers were wounded, in a terrorist attack. These attackers are basically a disgrace to civilization because they do not understand that freedom of speech is the beginning of education and civilization. Bangladesh must crack down on these killers of writers and thinkers if they mean to have a civil society. If the government does not, they can only expect worse to follow. Extremists only ever build upon what they get away with.
Update: Via The Friendly Atheist, the Bangladesh Home Minister calls these slayings "isolated incidents". This is patently absurd. Things that happen over and over again are no longer "isolated". And if he can't connect the dots, Ansar al Islam has thoughtfully already done that.
