Drugs and crime are less a matter of intelligence - or lack of it - and far more to do with circumstances.
Individuals deal with the things that happen to them in different ways - some well, some not so well, some downright badly - and we as the lucky ones (we have access to a cimputer, and the knowledge and language skills to us it) should offer our compassion to people who'se life choices may not be all they could have, or should have been.
And think that with a different set of circumstances, the less fortunate people on whome we pronouce could be us.... and maybe still will?
It's worth thinking about.
