Criminal activity: kind inspiring knave (10)
I believe the answer is:
carjacking
'criminal activity kind inspiring knave' is the definition.
I can't judge whether this defines the answer.
'kind inspiring knave' is the wordplay.
'kind' becomes 'caring' (I've seen this before).
'inspiring' indicates putting letters inside.
'knave' becomes 'jack' (synonyms).
'caring' placed around 'jack' is 'CARJACKING'.
Can you help me to learn more?
(Other definitions for carjacking that I've seen before include "crime?" , "Maybe taking taxi from driver" , "Vehicle stealing" .)
