You'll have to show me how a teacher once the shooting begins tries to calm kids or get them to safety and tries to open the safe in all the chaos.
You can open a biometric safe in seconds with your eyes closed.
Even if there is total chaos and you're thinking about getting the kids to safety first? You can say all you want sitting behind your computer in the safety of your home. How many teacher's are going to completly going to freeze?
I'm all for one entrance to schools with metal detector's and a carrying cop at the door checking people.
So if 20% carry guns and half of them freeze, so what? The ones who freeze don't help but they don't hurt and you still have the shooter not knowing who is armed.
Also "freeze" is not binary. A teacher may freeze to pursue the shooter, but they may turn around and shoot when the shooter walks into their classroom. Either way, they are a risk to the shooter
So a cop walks in and sees someone with a gun without knowing a 100% who the shooter is, bang that teacher is dead. Doesn't matter the teacher is yelling I'm a teacher, how the hell is the cop suppose to know? Bang your dead teach.
That is an unlikely scenario.
There would be training so you could avoid those situations.
And the cops are going in with the knowledge that there are armed teachers.
They could even announce a code word over the intercom telling the teachers that the police are on the scene.
Yes, still, it could happen no matter how much you train, I concede that.
What's truly bizarre about her argument is that she is choosing to avoid the risk of an accident rather than try to stop someone actually aiming and shooting at people.
You think she'd suddenly get that if she and/or her family were in the building? Maybe the risk of an accident is worth actually trying to stop the shooter?
