You cannot Draw Fast Enough to Stop a Shooter Who has Fired

I changed my mind on what I said last night. at least in part. You cannot draw fast enough to catch a bullet that has already flown. So, if I say your policing effort needs to equal the threat, what can we do to make our police effort equal to the threat that there might be a school shooting? If you have a police officer stationed at the school, will that stop the shooter? Well, normally, not even if the officer is right on the school grounds, he still won't be able to reach the scene before the shooter has fired and killed someone. As I said, you cannot draw fast enough to stop a gun that already fired. So, if an on-site officer is usually going to be too far away even if he is in the room next door, what if we gave everyone a gun? What if the teachers (or maybe even the students) had guns? It still wouldn't be fast enough. They wouldn't draw fast enough to stop the first shots. Yes, having guns there does cut the shooting short, and this is of great value. But, if the goal is to make your policing effort equal to the threat, you want to stop the shooter before he has killed anyone. So, if you policing effort is to be equal to the threat, you will need to take the weapon away from the shooter before he can use it.
So, consider gun bans, if you will. Trouble is, you have the Second Amendment to deal with. Many (if not most) feel the Second Amendment does not allow for a ban. You also have the argument the shooter might get a gun despite the fact they are illegal.
I think I'm back to liking metal detectors in our schools. Metal detectors are working at airports. If we are looking around and seeing what is working, this is a proven defense.
Now, I'm thinking one of the reasons we are not moving quicker towards metal detectors is that some believe that they, too, are a form of gun control. Others oppose them simply because they -- in the verbiage being used -- turn the schools into prisons.
As for the first reason -- the thought metal detectors infringe on the right to bear arms, I do not hold with the thought. You still have the right to bear a gun -- to own it and carry it around with you. You just cannot take it onto someone else's property if they do not want you to. Their rights trump your rights.
As for the second reason -- metal detectors turn the school into prisons. If the need for protection is severe enough, you take the measures, anyway. Call it turning the school into a prison, if you will, but if it will save lives, I think it must be done.
