A few number of United state city, the curfew is imposed to control the teenagers and do not allow them to walk at night without their adult.
I strongly believe that, the crime rates are increasing rapidly each day, especially at night. There are more likely to presence of offenders after sunset to carry out crime and ask teenagers to be involved with bad people when they are not supervised. as result, adolescent become more targets since they are more willing to try new things such as smoking, drug. Moreover, they lose their thirst for study, caused to stay away from academic achievement and career prospect. Hence, it is always safe for them to be inside during this time.
Nevertheless, some people believe that by imposing curfew on teenagers restrict their personal freedom and curtails their ability to engage in activities which contribute to their personal growth and development. then they are not given opportunity to explore their interest and participate in nightly event to learn essential life skill by themselves.
To conclude, I think that it is not safe for youngster to roam around alone at night as inappropriate atmosphere and people can harm them in their hours need. Thus everyone should follow this rule for their benefit.
