The Curfew is not being enforced, imprisons you, and does not prevent kids who are over 17 to commit crimes. There is always no one to enforce the curfew, and it is hard to enforce. You feel as you are in a prison, you should have control over your own life, and government should not tell you what to do. Finally, kids 17 years and younger do not commit crimes.
Curfew is not possible to enforce because you can not tell by just looking at someone and saying that they are 17 years or younger. In addition, since this is a free country, you do not have to have an ID with you all the time. For example, a Police Officer is walking on a street and sees several teenagers going on the same side. He can not tell whether they are 17 years or younger or not. Police Officer will not even bother to stop and ask anyone for an ID. Since it is not possible to enforce the curfew at all times, during the night, city is spending tax money for something that is impossible to enforce.
Curfew makes you feel imprisoned since you can not leave house for parties or be at one of your friend's house for long time. Lets say that I have to get some programs for computer from one of my friends and it might take a long time to do that. So after I finish and it will be past midnight, so I have to violate the curfew because it is too late and everyone is sleeping. By reason of an emergency or some kind of deed that might be lengthy and will violate the curfew, it might be impossible to obey the curfew.
Finally, kids who are 17 years of age and below do not commit crimes. I do not know any criminal who is less than 17 years of age or less since you are limited in transportation and money. Kids who are 17 years of age and below do not commit crimes, therefore spending tax payer's taxes for something that will have no use at all.
The Curfew is not being enforced since it is hard to identify the persons by their looks, puts an end to your fun, and does not prevent kids who are over 17 to commit crimes. Since there are no police cars given order to look only for curfew violators, it is going to be a drag to check someone. Some districts do not have a curfew, but others do, so if you go to a party in one district and you are from another, you might violate the curfew. All the kids that commit crims, such as burglaries or robberies, may have an adult with them, and curfew will not stop the crime.
