Here's a video of right way to teach kids about guns. Since there are so many guns around, it's a good idea to teach kids the right way to handle them in case they encounter one along the line somewhere.
When I was 5, I remember my dad holding the 20 GA to my shoulder and we fired a few rounds at an old tea kettle. Seeing the the destruction of the tea pot and feeling the recoil gave me instant respect for guns.
With all of the shoot-em-up video games out there, kids don't realize the real destruction guns can cause. Kids need to realize that they're not toys.
No man-trip UZI involved in the video below. Condolences to that family.
