Cruel and pointless to confiscate drone (8)
I believe the answer is:
inhumane
'cruel' is the definition.
(similar in meaning)
'pointless to confiscate drone' is the wordplay.
'pointless' becomes 'inane' (I've seen this in another clue).
'to confiscate' indicates putting letters inside.
'drone' becomes 'hum' (drone can mean to make a humming sound).
'inane' enclosing 'hum' is 'INHUMANE'.
'and' is the link.
(Other definitions for inhumane that I've seen before include "Heartless" , "Cruel" , "Callous" , "Not compassionate" .)
