The technology exists to prevent other shootings like this. Is this possible?

The New York Police Department, with assistance from the Pentagon, is testing a scanning device that can remotely detect concealed firearms, Police Commissioner Ray Kelly said Tuesday.

The device measures natural radiation emitted by people and can detect when this flow of energy is impeded by an object, such as a gun.

"This technology has shown a great deal of promise as a way of detecting weapons without a physical search," Kelly said in a speech before a police group in Manhattan.

Known as terahertz imaging detection, the technology functions similarly to night-vision goggles, which detect infrared radiation. But unlike much infrared radiation, the terahertz wavelength is not blocked by clothing.

"With terahertz, you will be able to identify a gun as a gun," said John Federici, a physics professor at the New Jersey Institute of Technology.

What about one of these Long Distance Gun detectors set up at the only One Way entrance of schools?
Maybe? they could build Pre-Entry hallways that self lock if guns/weapons are detected - trapping the offender inside of it
until someone could come and check it out. All other entrances would be self locking and function as exits only.

What do you think?

1. I don't think Lanza bothered to conceal anything

Those guns were out and ready and even if gunfire detectors had been installed in that school, by the time the cops got there it would have been all over. Locking the classroom doors might have slowed him down, but that depends on how much glass there was in the walls next to the hall.

2. He broke out a window to gain enterance

We can't and should not make schools like prisons
