Should Teens get Adult Sentences for Adult Crimes?

In my current article, (Teen gets Life in Prison for Murder) there seems to be definite disagreements between professionals in the legal system of North America. Some believe that if you're underage, if you do an adult crime, you adult time in prison. What do you think? Maybe you're from North America and you're reading this. What are the laws from the society and culture you are from? Do you agree with those laws? What would you do if the person under age were even younger than a teenager? Where would you draw the line? What do you believe is fair in this situation? Let me know what you think. Gloria Cowdery
