Violent politics, again

A student, Department of Mass Communication and Journalism, University of Dhaka
Tarique Rahman got hurt in police custody, and some BNP-linked students on DU campus demonstrated for his immediate release. They put taxicabs on fire, and an innocent man was killed at Nilkhet. The same type of violence was seen near Dhaka College also. What will happen to the families of the person who was 'killed'? And what about those who lost their earning capability by losing their taxicabs? This type of violent politics must be prevented. The people responsible for today's (25.08.2008) incidents must be punished. Otherwise, personal gain oriented politics can't be stopped.

How can we protest this type of unwanted death due to unwanted politics? We have no words left to condemn such politics of vandalism and killing. A frustrated citizen, On e-mail
