A scoundrel actor's caught out with troublemakers (9)
I believe the answer is:
agitators
'troublemakers' is the definition.
(agitator is a kind of troublemaker)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for agitators that I've seen before include "revolutionaries" , "Rabble-rousers" , "We wind up" , "A gait rots the stirrers" .)
