Introduce knife arches in every secondary school!

Background

I would like funding to be made to every secondary school to install knife arches.

Additional details

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.
