You receive an emergency alert: "BALLISTIC MISSILE THREAT INBOUND. SEEK IMMEDIATE SHELTER. THIS IS NOT A DRILL." What do you do? How do you think your neighborhood will react? What memes be on Lemmy?
I would not believe that message, because real warnings would not be that specific around here, and they also would never add that funny phrase " this is not a drill"
(Actual drills outside of the military are announced at least several days in advance, if they expect people to cooperate)
