Yes, times are changing.
When I worked for a major corporation in Salt Lake City, about 1980 all of us in the office were shooters. I remember numerous times when we would bring guns to work for "show and tell".
One day the manager said "Charlie, come here, got something to show you". Went into his office and he showed me a new Beretta pocket pistol he had just acquired. Others in the office brought S&Ws, Colts, etc. Yes these were the "Golden Years."
I also remember taking a handgun to downtown SLC to take to a gunsmith. Carried it inside my brief case on a city bus. Also purchased a couple of handguns downtown during the noon hour and carried them home on the bus.
Later, I went back to being a school principal and remember one time I took some guns to school, to put in the safe, for safe keeping when I left town. No problem.
At the last school I was principal, I remember taking my Ruger Security Six to school, to put in my desk, because the town nut case was coming in to raise hell.
(Later this scumbag killed his wife. That's the kind of clown I was dealing with.)
Also at this school I had two students bring guns to school. One boy was in the third grade and brought a "suicide special" break action, cheap .22 to school. It wasn't loaded. He just had it out on the playground at recess. He got suspended for the remainder of the year.
Next case, a fifth grader had a cocked and locked, cheap, .380 auto in his jacket pocket. He had been showing kids how to move rounds through the action out on the playground. He got suspended for the remainder of the year and I never saw him again.
That principal that made the big deal out of the plastic action figure should have been publicly bitch slapped. That is off the chart.
