Mob violence is emerging as a serious law and order problem in India. By giving suitable examples, analyze the causes and consequences of such violence.

Causes

• Rumour and identity: caste honour, religious insult, and cow-protection vigilantism have driven lynchings (for example Dadri 2015, later Alwar–Pehlu Khan 2017, and similar cattle-transport attacks). The trigger is often a forwarded clip, not a verified crime.
• Political polarisation and a sense that the crowd will be protected if it matches the local majority; weak, delayed First Information Reports teach that lesson.
• Communal riot systems: Muzaffarnagar 2013, older Gujarat 2002 and Delhi 1984 anti-Sikh killings — organised mobs, not spontaneous strangers, with rumours as fuel.
• Caste atrocity as public spectacle: Khairlanji (2006) and other Dalit lynchings show honour and land, not only “sudden anger”.
• Witch-hunting and kangaroo justice in parts of Jharkhand, Odisha, and the North-East: the mob as a substitute court.
• Economic panic: run on a shop, attack on migrant workers (Assam and Gujarat-type “outsider” violence), or a crash in a commodity blamed on a community.
• Policing gaps: understaffed rural posts, poor forensic and cyber skill against WhatsApp rumours, and crowd-control that arrives after the filming is done.
• Unemployment and young men with time; a mob is cheap to assemble where jobs are not.
• Cinema and livestream reward: status for the person who hits on camera.

Consequences

• Right to life and equality (Articles 14 and 21) fails in public; minorities, Dalits, migrants, and women in moral-policing crowds are the usual bodies.
• Rule of law: if the mob is faster than the court, private revenge becomes normal; due process dies.
• Law and order spiral: retaliatory riots, curfew, and a police force that then uses excessive force or, conversely, stands by — both destroy trust.
• Economy: bandhs, burned trucks, closed mandis, and tourism and investment flight from a “riot-prone” district. Migrant labour leaves, which hits construction and services.
• Social: ghettoisation, school dropout after a riot, and a generation taught that identity is a weapon.
• Federal and international: army flag marches, damaged India’s rights reputation, and a thicker hate-speech load on the next election.
• Policing morale: officers who register cases against a powerful mob face transfer; officers who collude teach the next mob.

What the examples jointly show

• 1984 and 2002 show State failure or worse when the crowd is politically useful.
• Dadri and cattle-lynching cases show everyday law-and-order collapse on a highway, not only a once-a-decade riot.
• Muzaffarnagar shows rumour plus election timing.
• Without fast arrest, video-based prosecution, rumour-rebuttal cells, and political cost for patrons, examples will only multiply.
