I made my guns safe around my kids with an education program that began as soon as they could speak.

When my daughter was in kindergarten we were at a gun shop. One of the clerks handed someone a gun and my little one started yelling, "He didn't open the gun first!!" Embarrassed the clerk but the S&W rep who was there at the time was impressed and gave her a 686 pin that she still has 25 years later.

I had a gun shop clerk tell me that they didn't always open guns because they "knew" that the guns were unloaded. How does a five year old have a better handle on the rules than a "professional"? Regarding unloaded gun in gun displays, there's a video on youtube of a guy being handed a gun from a display case, it isn't cleared, and the guy blows a hole in his hand.
