Yep. And knife crime isn't something you solve by declaring it a national emergency.
It's endemic; a cultural issue. Police are underfunded. Prison doesn't work. We ended up in a situation where too many kids had too few prospects outside of criminality, and knives became a way of life for them. Then you had so many shitbags carrying, that kids who may have never considered carrying a knife before were left thinking they had to, and they became the default way of solving problems.
That's not an emergency - it's a prolonged societal failure.
