This secret footage of a hate-filled racist rant helped the jury to condemn Gary Dobson and David Norris in the trial of Stephen Lawrence's murder on Tuesday.
A year after Lawrence's fatal stabbing, in 1994 police installed a secret surveillance camera at Dobson's flat in Eltham and this is what they saw.
Dobson was heard bragging that he had threatened a black colleague with a knife.
Norris was then filmed acting acting out violent crimes and discussing with relish torturing black people. He boasted at point that he wanted to "skin a black ****" and "blow their two arms and legs off".
