Actually, I'm thinking of somewhere else. Redhill Court was where I was thinking of, a bit closer to me.
There was a non fatal stabbing just across from Palace Road estate before, on Roupell Road. That's within the past 8 months, I think.
If you get the chance, there's an interesting episode of 24 hours in Police Custody about knife crime. Some kid, apparently never in trouble, took a kicking and subsequently carried a knife to defend himself. Flashed it at an aggressor who contacted some harder nuts who then turned up and murdered him.
The whole knife culture is nuts.
