almost exclusively applied by London thieves to a plain-clothes man, or a
 nose . 1967 C. DRUMMOND Death at Furlong Post v. 63, I had to give the
local P.C. a lift. I dropped the pig at Packenham. 1970 Times 7 Aug. 4/7
 Pig  is slang for a policeman and the defence says that the word  pig  was
scrawled over the doors of the house after the killings.
