RE:Deter, detect, defendI was thinking about this earlier. I’m no expert but it may be possible to install patscan sensors outside of the school, hidden in plain sight. (Considering their size) Maybe along a walkway towards the entrance of a school... inside a fake rock or garbage can about 20 feet from the door. And when a weapon is detected, the system will automatically lock the doors to the building. Again I’m no expert, just trying to think outside the box on how they could apply this tech to real world situations.
