Why did the sub pull the fire alarm???

Student witness who called one of the TV stations said the sub pulled to alarm to a get everyone out of the buildings and alert everyone that something was going on.

[Whether that was the right thing or whether cover-in-place will likely be debated by experts. Which would save more lives?]

Subs should be trained in active shooter drills. Most have no clue. Pulling the fire alarm makes quick targets. Unreal.
