State and explain four reasons law and order is needed in a community

In politics, law and order (also known as tough on crime and the War on Crime) refers to demands for a strict criminal justice system, especially in relation to violent and property crime, through stricter criminal penalties.

Explanation:

In modern politics, law and order, also known as tough on crime and the War on Crime, is demands for a strict criminal justice system, especially in relation to violent and property crime, through stricter criminal penalties. These penalties may include longer terms of imprisonment, mandatory sentencing, three-strikes laws, and in some countries, capital punishment. The War on Crime has been credited with facilitating greater militarization of police and contributing to mass incarceration in the United States.[1][2]

Supporters of "law and order", generally from the right-wing, argue that incarceration is the most effective means of crime prevention. Opponents, typically left-wing, argue that a system of harsh criminal punishment is ultimately ineffective because it self-perpetuates crime and does not address underlying or systemic causes of crime.
