Since the 1980s, the term zero tolerance means a philosophy of illegal behaviour that promotes severe penalties, regardless of the individual circumstances of each case. The zero-tolerance policy focuses on drugs and weapons and has been implemented by most school districts in the United States. Two federal laws led to zero tolerance, but state legislators were also willing to write similar strategies. Advocates of a zero-tolerance policy say they promote the safety and well-being of schoolchildren and send a strong message of deterrence. In addition, supporters believe that strict adherence to this policy ensures that school officials do not treat children differently. Critics of zero tolerance believe that the policy of inflexible discipline produces harmful results. In addition, school administrators failed to apply common sense in the application of zero tolerance, which led to the expulsion of children who brought to school objects such as an aspirin or a plastic knife. Donations` approach, we are told, has significantly reduced the time it takes to fill vacancies. But if Don handles the vacancy and replacement costs, he should see the cost of redundancies unnecessary.

It should also recognize the need to focus concretely on the correct rules and sanctions that are useful, rather than relying on generalities such as “zero tolerance”. The zero-tolerance police are at odds with community-based crime prevention and crime prevention efforts. In all cases where street battles are considered by citizens to be brutal, suspicious, militaristic or biased, citizens are prevented from playing an active role in local education and crime prevention initiatives, in cooperation with the police. This may be why communities that need neighbourhood monitoring programs most often are least often populated by active residents. The zero-tolerance policy has been adopted in schools and other educational institutions around the world. The policy is generally promoted as a prevention of drug abuse, violence and gang activity in schools. Common zero-tolerance policies concern the possession or use of drugs or recreational weapons. Students and sometimes staff, parents and other visitors who possess a prohibited object or who, for whatever reason, carry out prohibited actions, are automatically punished. School administrators are prohibited from using their judgment, reducing harsh sentences to be proportionate to minor offences, or considering a worsening of circumstances.
