The population of crazy and imbalanced people continues to grow. Folks growing up in fractured environments with no proper parenting, structure, discipline, love, etc.
Actually, they have always been there. Sure it waxes and wanes somewhat, but it you look at most metrics it has actually gone down since 1990. I preface the rest of my post under the assumption that depression/suicide/mental health issues are endemic and will remain with us.
These conversations tend to be more emotional and lacking in specification. Gun Violence comes in several iterations. You have the personal ones, where the shooter and victim are well known to each other. You have the economic ones, where there is money being contested like in the drug trade and then you have the mass events like we just saw. Each type has a different genesis and differing options to reduce.
Each of these types are made worse by the amount and intensity of the weapons available.
Without access to "military style" semi-automatic weapons with specialized bullets the later (mass events) is severely contained.
But, we already have a ton of this type of weapons and bullets on the street.
Personal violence has always been with us and is hard to contain because it can be done with one's hands or a knife, etc. So probably will always be with us.
Economic gun violence can be contained, but we need to take away the "profits." Legalization and regulation of drugs would go a long way in reducing this.
The question has always been are we, as a country willing to act in ways to reduce gun violence? So far the answer is no..............we know what needs to be done, but politically can't make it happen.
So we talk in circles around it, hand wring, and it just continues.
