Due to rise in unemployment rates may cities have seen a significant increase in criminal activities. There are certain areas in US where local counties have implemented curfews at specific time, not allowing teenagers to go out unatteded by an adults. I see it as a positive response as youngster are the easy victims of crime.
At the heart of the issue is the fact that the local police are short staff in many states in US, susequently leading issue handling the crime. To address this problem, local authorities have imposed some restiction to control the crime. They insist very minimal outdoor activities after specific hours and have also informed parents to accompany childrens while going out.
To examplify, Mesa county in Arizona have implemented curfew after 6 pm to get control over drug trafficing issues and had seen considerable decrease in crime rates.
Secondly, the low income neighbourhood in US have seen a subsequent raise in crime rates especially in nights, where gang activities take over the area. In such cases the obvious target are youngster, as they are not self consious about rights and wrongs, so they become a easy victim of crime. If an adult is accompaning them they can protect and guide them. For a instances, there are places near US-Mexico border where kidnapping is a common problem, children are there major target so to avoid that, curfew is the best option.
In conclusion, I can say that authorities can not be everywhere and they cannot control all the crime, so implementing curfew is the best way to protect teenager to become a victim. It is for their own safety and should be taken as the positive change.
