Introduce knife arches in every secondary school!

There have been far too many children lost way to early to knife crime. We need to provide a preventative in school, 1 been educating them and the other been a knife arch to detect anything before any actions can be carries out. I am a mum of a 14 year old boy so life is very scary in recent times, worrying to send my child to school and along with many other parents, a knife arch can make a big difference and prevent such crimes within our education.
