Introduction In a country like India, with such a huge diversity in the population on basis of various factors like religion, caste etc., criminal events like riots are bound to happen due to disputes among communities which have been living together for centuries and has been violent against each other at point of the time or other, in history. Definition, Cause and Medium of Propagation of Riots Riots are like very fast propagating Epidemic disease in a population living in a region which is : caused by - Trigger: Any sudden event or accident, Information (true or false) which can agitate people to cross their threshold of self-control. False rumors in many cases. As riots progresses, the information of violence itself become a trigger. carried by - communication medium like news channels, print media and word of mouth communications among people propagating with physical movement of rioters informing people by face to face conversation, using loud speakers or via communication devices like Mobile, Internet etc. Dynamics, Behavior and Characteristics The trigger which may be based on any isolated incident which may include hate crimes committed by one community against other, infects the people of one community as they receive this information and they may decide to become violent. Hence they may start targeting the population of other community mentioned in the trigger. This target population is called susceptible. The susceptible may have received this trigger and information about approaching infected violent people. If susceptible become aware earlier about coming danger, they can take steps to protect themselves. But this itself is a challenge as people don't expect such type of sudden attack and our administration structure is not that efficient in swift actions to stop spread of information and quick disposal of security forces . A common man doesn't expect that few people will suddenly come at his doorsteps with swords, petrol etc. and vengeance in their eyes with intentions to kill him and his family. A mob often become much more violent and more heinous crimes happen as people get into frenzy seeing each other committing violence together. One should keep an important factor in mind that as the trigger rumor or information of riots spreads, population of susceptible and infected also increase at much faster rate. To make a recovered or immune section from riots, more number of susceptible population as to be brought under the protection of security forces from rioters . To achieve this, government needs a considerable number of security personals with proper riots control equipment, who can do their duty of protecting all sections of people, no matter which community they belong to irrespective of their reaction towards emotional condition prevailing in the society affect by riots. To understand the emotional dynamics in riots, one should consider emotions of rioters along with that of Security personals as it directly affects the efficiency and willingness of these personals to protect the susceptible and stop the infected. We can't ignore the emotional aspect and human factor of decision making of Security forces in the riots. Also, to control the riots in minimum time period with minimum casualties, high efficiency and swift deployment of Security forces is needed. Conclusion In case of riots in India, especially in regions which has bloody history of communal riots backing decades or centuries ago, all these factors should be considered. This helps us in rational, unbiased and logical understanding of emotional crimes. This in turns helps in quantifying and measuring various aspects of spread of riots in the region. Efficiency of various governmental measures by studying the previous riots can help us in determining better strategies to control riots, important areas to invest in resources required t o handle the riots and to save valuable lives, property and last but not the least, national honor.
