Topic: We should adopt a zero-tolerance policy in schools
Zero-tolerance policy works- Think of schools three decades ago, when the policy was prevalent. As a result children were obedient and disciplined, as opposed to students' behaviour  today, using moderd soft approaches in schools.
zero-tolerance reinforces behavioural patterns and does not address underlying problems that lead to the situation
zero-tolerance results in an overly disciplinarian approach, and is unable to distinguish between all the subtle gradations of rule-breaking.
zero-tolerance weeds out those that can cause future harm
Zer-tolerance policies can be unjust towards someone who is wrongly accused of breaking the rules.
