Police officers are one of us and deserve our respect. They can pass on their insights about the violence they all too frequently observe. There are many approaches to reduce violence by adult offenders. Many adults need basic education-literacy first of all. There can be more classes in public schools for adults.
Adults have to learn communication skills-to listen, and to speak in ways to be heard.
They need to learn practical goal setting. Adults also learn well from peer educators. Punishment through prison time is not enough to teach adult offenders to be responsible for their actions. Adults need mentors and positive role models as much as children do. Peer couseling like that provided by M.E.N. is very effective.
