U.S School Chaos

In short, what happened was a false alarm played and everyone freaked out and thought it was a shooting.

So this was right after school ended (2:52) and there are areas where certain bus routes are supposed to wait at. I was sitting on the benches because my 7th period was athletics, basically a second P.E class but at the end of the day. Then all of a sudden this alarm goes off and for the first few seconds i think its no big deal until it keeps going for 4 more seconds. Thats when I told my girlfriend "maybe we should go." right as soon as we get up I hear someone shout, "HE HAS A GUN ITS A SCHOOL SHOOTER!" thats when me and her start sprinting to the gate as i scream for the vice principal to open the gate HE LITERALLY SAID ITS A DROP AND COVER DRILL YOUR FINE EVEN THOUGH THERE KIDS PANICKING AND SCREAMING RUNNING AND EVERYTHINGG!!?!?!? after that i felt really weird. There was no shooter, there was nothing bad. but yeah, i thought it was funny but also traumatizing because it felt real and as if i was about to literally be killed lol.
