If someone chews a Pop-Tart® into the vague shape of a gun, shut-down occurs.
Yes, this happened in Louisiana...
There were bomb incidents 35 years ago when I was in school. The students would be sent home. Parents may have been notified. None of it made the local newspaper or radio (there was no local tv station in our city).
Often the threats were called in (and hoaxes) say during midterms to void the testing.
But there were several incidents with small bombs being discovered or going off.
The media coverage these creeps get brings on more such activities.
35-40 years ago there were tylenol tamperings/poisonings and people holding McDonald’s customers hostage while firing off shots. Those got a lot of media coverage and there were copycats.
There were thousands of bombings throughout the 70s from Weather Underground and other Far Left hate groups.
