terror sleeper cells in the south

who started the provocation originally in tamilnadu can be a subject which will never yield any outcome.
if there is a speaker who offends people of another religion,his speeches can be monitored and if the offence continues,a complaint with evidence can be submitted to the police.

it is a matter with a simple solution.
the same type of situation,but many times worse prevails in kerala.
a meeting between the concerned organisations and a thrashing out of all grievances must be initiated by the congress and the left,acting together to prevent the violence.
