There is a serious problem with the fact that a child of 12 is stealing cars, and is not being disciplined. If it was my child, for one thing, the first car wouldn't have been stolen, but in the hypothetical situation that he/she stole a car, then I would make definite sure that it would never happen again.
Different factors have to be taken into account when dealing with a 12 year old boy. In today's society, children of a younger and younger age are being bombarded with images and messages that really DO have a subconscious effect on the way the behave. For example, TV. One of the movies that I have recently watched was the third Austin Powers film, "Goldmember". I watched this at a party. At this party were children of all ages. By the middle of the film, most of the children were watching the movie as well. After the movie was over, all you heard from the majority of the children were the cruder lines in the movie. It made me a little queasy when I had to listen to one very (usually) precocious 7 year old girl run around yelling, "She shat on a turtle!". Is this the type of information we want to give to the desicion makers of tomorrow?
So there is TV. One of the major influencers on the future generations. But that "great evil" pales next to the number one killer of innocence and childhood. The family. The parents of the 12 year old boy who stole the cars should be checked out. The kind of neglect that lead to the child's obvious interest in crime as a means of attention is absoulutely horrible. I think that the background of the parents should be investigated to see why they allowed this thing to happen.
I don't think that, however, anything should be done to the boy without the express permission of the parents. Definitely, resources such as reform schools, counselling, and shock treatments (sorry---bad joke

) should be provided for the parents to look at. I think that after they have been presented with all the materials the parents should be offered funding to help them pay for the more expensive modes of treatment, and then we wait to see what they want. After all, it is their choice. If they want to allow the boy to continue to break into cars, and to endanger his life, and the lives of others, then that is their choice. They will have to deal with the consequences, but that is the beauty of living in a free country. They can choose to shoulder that responsibility. And if they should choose not to provide help for their son, then all we can do is wait for the next time around when the boy is no longer a minor and is put in jail. Then we can tell him that it is his choice, not his parents, and see if he chooses to get help then.
