1969 in Walpole, Mass.
(between Boston and Providence, RI). I was in the Dramatics Club production and needed a rifle for a couple of scenes.
No problem - I brought my Ithaca .22 to school for about 5 or 6 weeks. On the bus. With blanks. Stored it in my locker, then strolled up the hall to rehearsal, carrying it in what was obviously a rifle case.
Fired same on stage in numerous rehearsals, plus the two actualproductions - in school, during class time, with school staff present. Never asked permission, and the only person questioning me that I can remember was the bus driver on the first day. Once he saw that all I had were blanks, he was happy.
Don't know what the law was then (and never gave it much thought); it is seriously illegal now.
Note: To my knowledge (and I still live in the area), there has NEVER been a shooting in any school in that town. A few years after I graduated, however, there were kids freaking out on Angel Dust that required 2 or 3 cops to subdue them, and this happened on several occasions. Funny, I thought that stuff was illegal..........
