Knife amnesty - is it worth it?

[Callisto]

It always strikes me that although it is a very good thing that there will be less knives 'on the streets' the people who would actually knife someone are the people who won't be handing their knives in. Like the various gun amnesties - good that there are less guns but won't stop gun crime. What does everyone else think?

We had one student stab another at work last week. It's usually teenage boys who carry these things. Teenage boys are not known for their measured response to provocation. Take away the weapon the worst that can happen is a broken nose.

I do agree Slug, but will they hand the knives in do you think?
