When I was 15 years old, I was called callous and cold for making a statement about how if someone died, even a kid my age, from overdosing on drugs or getting killed in a car crash driving drunk, it was their own fault. I know if you're just a kid experimenting with drugs, especially the hard ones, you have no idea of what your safe limit is, but there is so much information out there about drugs, that if you make the choice to use hard drugs or drink until you're falling all over yourself, you are the one responsible for the consequenses of your behavior.
Of course, with kids, the parents also have to be involved in their kids lives enough to know what they are getting into. That's just responsible parenting.
The article you wrote, about how everyone has to pay for the actions of a few individuals, was a good one. People need to be held responsible for their own actions and behaviors and the results that go along with it. The non-guilty shouldn't be punished for other people's actions.
