Gun violence is just one aspect of violent crime as a whole. It makes no sense to focus on "gun crime" without focusing on the roots of violent crime in general. Those roots include a general sense of entitlement, a lack of respect for the community and tolerance of anti-social behavior. That's been evidenced in blighted communities in every country and of every race.
There is no classification "gun violence" it is a propaganda invention of gun control to stigmatise firearm ownership. It is best to avoid using such irrelevance and obvious bias in serious discussion.
Let me help with a better idea of the causes of crime.
The causes of crime are complex. Most people today accept that poverty, parental neglect, low self-esteem, alcohol and drug abuse are all connected in explaining why people commit crimes. Some people are simply at greater risk of becoming offenders because of the circumstances into which they are born.
These are all social problems dealing with the results of poor outcomes for life. Poverty, employment, low self-esteem, parental neglect, housing, lack of viable opportunity, education...... leading to crime as a means of support and drug taking as a means of escape.
Boredom, social exclusion, gang culture, fatherlessness....
There is no single cause but all lead to stress on the individual
Gun control can repair or reduce none of these which is why all gun control laws will fail.
What gun control does is deflect spending that should be addressing these social problems into a bottomless and ever increasingly voracious pit.
How much more proof is needed that there is not in the whole world one single gun control law that has reduced crime, the supply of guns to criminals or increased PUBLIC SAFETY. Not one claimed success can be repeated with the same results. It is physically impossible for gun control laws to do this as there is no known causal relationship. Nor can anyone explain how guns could possibly cause crime without a magical element or referral to the paranormal. What we have is people with an induced belief no different to the flat earth or a belief banning alcohol and drugs will rehabilitate people.
