I was totally amazed when my child was in high school. I would drop by school periodically to see how thing we're going or to go to a medical appointment, because of a stroke at an early age. The school was like a revolving door. There were always police on school grounds picking up kids who had broke the law. I was told that this occurred every day routinely. Sometimes there were several cars there at a time. So no based on what I saw and additional armed monitors are not needed. Police are there now they just need to be kept informed.
