When I was stationed overseas, we had Armed Forces Radio and Television service on base (which we affectionately called A-Farts, lol). AFRTS doesn't have regular commercials-- they have public service announcements on the commercial breaks. Some of these are adverts for National Parks and monuments, and others are what I'd categorize as educational good advice. We laughed about a lot of them, such as the one "Your eyebrows, wear them with pride!" However, there were lots of educational PSAs about good health habits and safety-- the importance of wearing helmets while biking or on motorcycles, for example.
I really wish we had that on commercial channels in the U.S. because things like gun safety PSAs could reach a lot of people and children in their homes. Good habits are the result of education and reinforcement over time. We have to stop pretending guns are evil, and teach ALL adults and children about what they are, how they work, what to do if you encounter an unsecured firearm, etc. What could be the possible HARM of teaching SAFETY as a strategy to develop confidence in the whole population? What possible BAD thing could occur from teaching safety measures and respect for gun handling?? It astounds me that so many are so opposed to even TALKING and TEACHING about this subject. The inaccurate propaganda rules the airways and scares ignorant people unnecessarily because of the extreme bias of the media. Particularly the propaganda of manufactured scary terms, like "assault weapon". There is no such thing as an "assault weapon". Every weapon can potentially be an "assault weapon" if used to assault.
Education, education, education WILL make a difference in behavior, over time. WE have to stop pretending the goal is to limit or get rid of guns as the solution to criminality and accidents. We have to act to make improvements where we can, and accept the fact that guns are, and always will be, a part of American society. We have to reinforce safe ownership for those who want to own, but not pretend guns don't exist by people who don't want to own them.
Look at seatbelt use since the 1970s, child restraints, and helmets, as examples. We have made huge improvements in health and safety with seatbelts, mandated child restraint systems, and helmets-- which many people laughed at as unnecessary decades ago. Education DOES work to change behavior. We have to stop demonizing guns and gun owners, IMO. When we make that switch, we will see a decrease in child gun accidents, IMO. But it will take years of education, and lots of public acceptance. Just like carseats, helmets, and seatbelts.
We can't fix all the social problems of lunatics and criminals, but where ACCIDENTS take children's lives, we CAN make a difference, IMO.
