Nowadays more and more teenagers do crimes. There are many reasons and theories for this, but there are not much ways to reduce teenage crime. Firstly, busyness at home and at school should be biggest. I think if teenagers would have trade, there would be less crime in the streets. For example: out of school activities, travels, and international organizations, or example: scouts, youth clubs. Secondly, there is a good law suppressive child till 16 years age walk in street after 222 o’clock without parents or other adult. Thirdly, government should arrange more free cultural shows, then teenagers will have more entertainments. Finally, I think in schools should be incentive for good studies. Then students could try study better. In conclusion, there are not many ways to reduce teenagers’ crime, and it’s difficult to know which of these ways is most effective.
