The U.S. is overly protective of children and young adults. We can't drink alcohol until 21 and many cities have curfew laws for kids up to the age of 16 or so. My city has a curfew for those 16 and under. They can't be out after 11 pm during the week and after 12:30 am on weekends.
Well, I don't know; why are 15 year olds walking the streets at 1 a.m.? Something is wrong there 99.99% of the time. I don't think they should be arrested though, just returned home. I had cuffs thrown on me for curfew when I was 16 or so. No arrest, but seriously, cuffed and thrown into a pen.
This kind of thinking, right here is a problem. The "something is wrong there" assumption is wrong all too often. The assumption that the situation requires cops is wrong too - the wrong thing is most likely a parenting issue and should be dealt with by parents.
Do not take me wrong, I do plan to restrict my kids movements in age appropriate ways and if they are out at 1 a.m. it better be for good reason and with my prior approval.
However, even if it is without mu approval, the appropriate punishment is not cuffing nor arresting them. That kind of thing should be reserved for potential criminals that are flight risk or about to be violent. Teaching teens that arrests are normal part of life and done for normal growing up infractions teenagers occasionally commit in all parts of world is inherently wrong.
"Should be dealt with by parents", I agree. Often, it is not, so the community has to do something. I don't mind a curfew for kids, but I don't think it should be a criminal offense either.
