At least 70% of the crimes, violence in world are out of frustration. Frustration out of poverty, not getting opportunities because they were born in poor black families in America who were made to work under slavery without getting paid. Unlike in India, there is no reservation in USA to compensate fofr the injustice done to thgese peopel.
People like you havee choice. Just because you are lucky and live in golden palace doesnt mean that every one else had these opportunities. These violent people are suicidal minded. That's why there is so much gun violence in America because it is aint worth living in America as a poor black. I know of at least three instances where people were denied jobs because they were black even though they were qualified and given some other excuses.
Just because you are lucky don't assume others misery is because of theiir own deed. Your theory holds good only for those criminals sho came from well to do families.
