There were bombs in schools (sometimes threats, sometimes legit devices in pipes or other things like beer bottles) in the 70s and 80s.
Didn’t make national news. Didn’t make local news. Never even heard who the perps were.
Also I don’t know of anyone being injured by the devices I’d heard about in school. We’d just be dismissed for the day for safety reasons.
There were thousands of bombings by militant leftists in America in the 1970s. Those did make the news cycle.
I was born in 75, but here in the 80s, these threats were unheard of.
It’s the same globalists up to the same crap. Only now they’re panicing because nationalism and patriotism are in the rise all over.
