Lee was jailed after shooting Pc Walters through the heart as he was being arrested at a flat in Ilford in 1995. He was convicted of manslaughter and jailed for 18 years - meaning he is now eligible for parole from Long Lartin prison in Worcestershire. Pc Walters's father, Colin, said: "I can't believe they might let him out after only nine years. Is that all that a police officer's life is worth? It's a joke."
