We agree! So it's a good thing no one is asking them to be. There is absolutely no expectation that anyone will run into harms way when a crisis erupts. But when one does, and a teacher has to decide to die, or let their kids die, versus fighting back, we want them to choose the latter. And in that situation we also want them to have the most effective means to fight possible.
Of course not. All adults who visit a school have to have a legitimate purpose for being there. That means that unless you are a parent or school employee, you have a very narrow range of adults who can be there - just like it is now. Nothing about this change to the existing law extends rights to a new class or group of adults to suddenly have access to a school.
And this initiative won't arm them. This is not a mandate or policy to force anyone to carry a firearm. What this DOES do is give those that wish to carry the ability to do so. It gives them the CHOICE!
Well, here's where some common sense and training is necessary. In most scenarios in which an individual is carrying, said person carries in such a way that no one but themselves is able to get the weapon. In addition, most experienced carriers will plan appropriately for the activity they plan on doing that day, and will adjust their carry (even to include a decision to not carry) based on whether or not they can do so safely. There are also types of holsters (level 2) which have locking mechanisms (not a mere strap) that prevent a weapon from simply falling out or being snatched away. Under 1621, school districts could require employees who carry to use such holsters.
I would submit that if there is a teacher for whom this is a genuine concern, perhaps they should not be teaching in the first place.
Now, if the argument is that we just don't know who may or may not flip out, then what is different than now? It is far more the case that anyone who decides to commit these types of acts do not do so impulsively.
Guns are tools, nothing more, nothing less. In good, trained hands, they pose no greater danger to safety than a pair of scissors. However, even more convincing is the fact that just across our southern border in Oregon, concealed carry on school grounds has been legal for roughly 25 years without significant incident.
