Woulda' been too dangerous otherwise.
Sniveling,
Whining,
Abjectly-
Terrified.
Remember the one teacher who died a Columbine?
Students called on cell phones and got medical advice on how to care for him until he died.
It was two to three HOURS until help came to them, too late for the teacher.
The SWAT team was out side the building for most of this time.
Had the SWAT team gone into the building that teacher might be alive today, but we will never know because he died while they hunkered down outside the building.
And those are the ones we're supposed to count on to protect us. The ones more interested in protecting themselves.
