Impunity corrupts analysts, essentially, making them unmanageable (6)
I believe the answer is:
unruly
'unmanageable' is the definition.
(similar in meaning)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for unruly that I've seen before include "Indisciplined" , "Not easy to control, disorderly" , "Rumbustious" , "Disposed to disobedience" , "'Boisterous, disobedient (6)'" .)
