My school years were in the 50’s and 60’s. I never heard about any school shootings at that time. But then I wasn’t allowed up past 8 PM and the news was three hours later. Didn’t read the paper seriously until my 30’s. I recently applied for SS and now there are guards in those offices and they check whatever bags you bring in for weapons of any kind. A man there had to go back to his car with a little pocket knife as it wasn’t allowed in the building. The guards wouldn’t hold it as they said if they did he wouldn’t get it back. Basically, it would be confiscated. These days, you just can’t trust anyone anymore.
