To lower gun deaths w/o restricting access. You have to understand first where gun deaths come from: suicides, accidents, murders, justifiable shootings. Suicides by far represent the majority of gun deaths. Most murders come from gang and inner city violence. Accidents often times are preventable, but not always.
1. I hope and pray that these mentally ill people who commit such crimes don't realize there are many other ways to be better at it. In 2016 Nice, France, a guy killed 84 and wounded 458 others by driving a truck through crowded streets. Most people have enough chemicals laying around their homes to make various bombs. What if someone poisoned a school's spaghetti? From a very warped perspective, we're lucky these jackholes are only using semi-auto guns.
2. Mental Illness - As a general statement, the US is pretty poor with dealing with mental illness. It's widely accepted that a large population of the homeless are mentally ill. Instead of helping these people we either ignore them and/or chuck drugs at them. We need better diagnostics, better recognition, better treatments. Appropriate interaction needs to happen among the general populace, firearm community, etc.
3. Technology/options - I do think that firearm companies should embrace and develop more safety tech. For example, palm/finger print identification on a firearm. Right now the technology is prone to failures.....which makes it less than ideal for life/death situations. However, if things could progress to the point where it can be reliable and prevent the possible "kid accidental discharge" scenario, it might be worth it.
And ABSOLUTELY I AM NOT mandating that all firearms should have this. I'm saying that in the future if the technology gets better/reliable, that consumers should have options.
Or what about less lethal technology that subdues the threat......for example the Star Trek "phasers on stun." Sure, we're talking about some fantastical things here, but why not? What if tasers get to the point where they have multiple shots, accurate, and extremely reliable? Once again, it'd be nice for Americans to have options.
4. Safety - It'd be nice to have significant incentives for people to take basic firearm safety or general firearm training. While certainly not aimed at the mass shooters out there, it might help lower the accidental happenings.
5. Parenting/Child Rearing - THIS IS HUGE, HUGE, HUGE. Kids are not being taught right/wrong or shown the consequences for their actions. They're not being taught good decision making. This SHOULD be the parent's responsibility.....and when the parents let their kids go off to school, the schools would aid in the rearing. Far too often, kids are getting guidance at home or at school.
6. Education - I think that every single year there should be a "LIFE" class in school. Kids should be taught how to weigh decisions, consider consequences, and act accordingly. Understanding the importance of participating in government and citizenry. Kids should be taught about various jobs out there......requirements (which includes going to college or not).....pay......etc. Kids should be taught about finances......investing/stock market, compounding interest, paying bills, college loans, what is insurance, what is a mortgage, free market economics, taxes.........understanding decisions/consequences to invest in the market vs by a Polaris Razor/bass boat. Kids should be taught some basic communication and relationship skills. Understanding why friends act like they do. Understand the differences between men and women. Understand and teach coping of bullying, etc.
7. Inner city/ghetto - Combined with all of the above, we need more police presence. We need to flood the areas of high crime. And not just police sitting in cars waiting for things to happen. We need officers to walk neighborhoods, smile, talk to people on porches, shoot basketball with kids in the park, incite community involvement, etc. Once crime starts to decrease, give incentives for businesses to start moving into the areas to stimulate economic growth.
If you do the following, gun deaths will reduce in time.....but it's not quick. And all without restricting access to law abiding citizens.
This would also address a number of other issues.
