Comments on political killings

Why do people in Kannur join political parties and kill each other? Is it for ideological reasons ? I think majority of the killings are done by professional execution squads. These are organized by local leaders of the major political parties. These leaders infuse their followers with hatred for each other. But why can't people think for themselves ? Why do they act as they being controlled by someone else ? It is said that the killer squads are protected by their masters. Usually unrelated persons are purposefully arrested. Thus the evidence will be flimsy and the accused are acquitted. Psychiatrist working in Kannur have narrated tales of the emotional problems faced by school children after their teacher was assassinated in front of them in the class room. But later we also happened to hear about killings done by the same political group. The parties only aim is to get public sympathy. They know how to get this sympathy into votes. I think there may be a high prevalence of Post Traumatic Stress disorder in Kannur district. It will be worthwhile to conduct a study.
A description of the clinical syndrome of Post Traumatic stress disorder is given in an earlier post on "Emotional trauma and dissociation".
