Wonderland has pointed gamesblog to this great anti-knife ad campaign from the Met. Alice's take:

The site is top quality, and the video is extremely well produced. The message, I think, is excellent. The target audience is clear - urban hoodie-wearing kids (popularly demonised in the UK on a regular basis). I think it could have a pretty strong impact on kids - it'll certainly speak to them... yup, I think the Met's being very clever here. Jeez, there's even a PSP version of the vid!

She's right. They've really done their research with this one.
