The increase in juvenile crime is due to the collapse of moral values. Children these days are exposed to tons of unsavory examples in the media, and their parents do nothing to stop this from happeing. They think that it is okay to be sixteen and pregnant, and that is why crime is increasing.
The increase is due to lack of father figures in the homes of young teens. There are plenty of statistics that prove this to be correct. Many don't know there parents or parent and so are faced to make decisions they would never have had too. It is said that babies who don't receive holding from parents when born become colorblind. It is the same with encouraging words from those who are supposed to love and protect you. The young people receive no guidance at home and so look for that guidance else where. Commonly known as the "street life".
