State crime (7)

I believe the answer is:

treason

(Other definitions for treason that I've seen before include "Betrayal (of one's country)" , "Betrayal of one's nation" , "Deliberate act of betrayal" , "Crime of treachery against the state" , "Disloyalty (to one's country)" .)

I've seen this clue in the Penny Press.
