It's not about singular/plural. "Was" is correct, however, for reasons described by Correcting Corrections, below.

Upon further review, the ruling on the field is overturned. I stand corrected, for the reason you state. Good article explaining the difference, which I (obviously) didn't know: http://grammar.quickanddirtytips.com/subjunctive-verbs-was-i-were.aspx

"How Mars May Have Looked if It *Were* Covered in Water"

I agree on the rarity. Campuses, and especially ones for little kids, are both safe and unsafe because they are a closed environment full of (mostly) women and children, two demographics that don't, statistically, generate a lot of violence. This makes them, most of the time, happy places with few worries of…

Well, if the teacher is prone to terrified panic and is incapable of not shooting bystanders, then he/she probably won't be one of the ones who volunteers to CCW.

You have surprisingly great faith in police officer training, and surprisingly poor faith in your fellow teachers' training.

So, rather than data, you cite, what, your feelings? "It's stupid because I think it is." I remember when my 17-year-old daughter said stuff like that. About fourteen years ago. It was adorable.

"There have been mass shootings at many of the locations you mention [Churches (in most states), Restaurants, Parks, Pools, Downtown areas on weekends and shopping holidays, Truck stops]"

And teachers regularly statutorily rape their students. I don't think the criminal excursions of either group offer much data toward the suitability of voluntary CCW in schools.

"There have been mass shootings at many of the locations you mention."

"Teachers DO have a unique stress proposition"

Your solution appears to be dying without attempting to fight back. Your fantasy of a noble, unarmed death is equally incomprehensible to me as my armed response is to you.

The two situations you describe are not dissimilar. But, unless you are arguing that the police should not engage mass shooters because they are not trained enough, I don't think I understand your point. If you would, please deselect your sarcasm mode and just state your point, please.

Completely agree. It was awesome.

Columbine, on the leading edge of the modern school shooter movement, was a failure for law enforcement because they had little to no training against an active shooter scenario. They sealed the perimeter and waited an hour for SWAT to arrive, by which time the rampage was over. Modern police are trained…

"Adam Lanza was wearing a military grade bulletproof vest"

So, yes, you are worried about teachers, your coworkers, snapping.

If that person has a gun in his/her hand and is firing, then my answer is "yes." If you take too long and get shot, you are no worse off than if you were unarmed and got shot.

I think if you met me, you'd be surprised. I'm soft spoken, not physically imposing, and easy to get along with. You'd never know I'm armed, and I wouldn't tell you. I'd rather not shoot anybody, so I go out of my way to avoid confrontation, often silently accepting real harm or imposition to avoid even a verbal…

Actual gunfight? Nope. Simulations? Plenty. I'm a former military officer and combat veteran (albeit in a jet) and a firearms instructor, as well as a shooting hobbyist.
