PFI Kerala bandh: Why `violent politics` in the name of bandh?

In protest against the raids and arrests, PFI has resorted to violence during the one-day bandh in Kerala today. This violent demonstration is taking place in many areas of Kerala. In fact, the National Investigation Agency and the Enforcement Directorate have raided the Popular Front of India's locations and its links in 12 states across the country including Kerala and Tamil Nadu.
