Doreen Lawrence (L), mother of murdered teenager Stephen Lawrence, prepares to speak to members of the media after Gary Dobson and David Norris were sentenced for his murder at the Old Bailey, the Central Criminal Court in London January 4, 2012. Two men who took part in the murder of black teenager Stephen Lawrence in 1993 -- a landmark case which exposed what an inquiry called the "institutional racism" of London's police force -- were given life sentences on Wednesday.
