If found this very interesting:
It’s important to understand the most common underlying factors that lead to violence: untreated anger, family violence, past history of violent acts, growing up where violence is used, and being young and male. To be clear, anger is not a mental illness. Hatred of others is not a mental illness.
It strikes me as probably true and gives us insight as to why Federal law against people who have been involuntarily treated for mental illness being banned from gun ownership is mostly useless and should be repealed.
A bigger issues is, “Can this this knowledge be leveraged in some way to reduce violent crime without infringing upon the rights of individuals?”
