Final answer:
The specific group of juveniles more involved in juvenile justice is not identified, but the issue is tied to increasing juvenile crime rates and ineffective rehabilitation, leading to suggestions that juveniles be tried as adults.
Step-by-step explanation:
The particular group of juveniles that has become more involved in the juvenile justice system than ever before is not clearly specified in the provided materials. However, discussing trends in juvenile offenses and incarceration might suggest looking at demographic or socio-economic factors influencing crime rates. The materials indicate that the number of juveniles committing serious crimes is apparently rising, and the facilities aimed at rehabilitating these juveniles are not achieving their goals, as a high percentage of youths continue their life of crime. One suggestion posed in these materials is that juveniles should be tried as adults to mitigate the problem.
The U.S. has witnessed an increase in incarceration rates since the 1980s due to 'get tough on crime' policies, with over two million people locked up in 2017. The criminal justice system faces challenges with effective rehabilitation and reintegration of offenders. Moreover, trends have shown that juvenile delinquency rates can be influenced by the social environment rather than ethnicity alone, suggesting that improvements in neighborhood stability could reduce crime rates among youth.
