Teenager's judge as an adult

I read two days ago the interesting article about :Should teenagers be judge as an adult?
They have to be responsible for their actions. The society establish rights and duties, that the population has respect. If teenagers makes a mistakes they have to be accused as adults. The society has to analizate three points : their background, the kind of crimes commit with the consequences for establish the judment. In my opinion the law has to punish the same way the teenagers and adult person with a few exceptions. The teenagers have to be clear that all bad action brings consequences.
