All you have said is correct.
The stats for Australia are very much the same, the problem is that young boys who have a bad home life, do vent-it later in life.
It is very small numbers who can (just let go, and have a decent life style).
I have worked with young people, and it always comes back to the home.
How it can be addressed, is worked out by better minds than mine! but the
problem is hard to fix,it starts very early in a childs life...and continues for years of just being around a violent lifestyle.
Later, it is seen by that boy as normal....and once again it all starts over again.But it also is not just about the violence, it is about being in a very unhappy home , one nearly void of all love and caring.
When any love comes it is embraced but just doesn't last too long.
Ultimately, the child grows up only knowing one way to live.
Classes are a very good tool, but with that one still has to be mindful that the guy has had a disproportionate life to start with.
The sheer 'psychology' is a giant issue, which needs attention over many years.
I have been horrified to hear some stories of abuse at such a young age.....
