Court that condemned murderer (3-6)

I believe the answer is:

cut-throat

(Other definitions for cut-throat that I've seen before include "Murderer - fiercely competitive" , "Violent offender" , "Ruthless in competition" , "Fiercely competitive - type of razor" .)

I've seen this clue in The Times.
