If censors get involved in science (9)
I believe the answer is:
forensics
'science' is the definition.
(I know that forensics is a type of science)
'if censors get involved' is the wordplay.
'get involved' is an anagram indicator.
'if'+'censors'='ifcensors'
'ifcensors' is an anagram of 'FORENSICS'.
'in' is the link.
(Other definitions for forensics that I've seen before include "If censors combined in medical studies for legal purposes" , "study of public debate" .)
