Choose jurors in the middle - it's shrewd and will give them a shock (11)
I believe the answer is:
electrocute
'shock' is the definition.
(give an electric shock)
'choose jurors in the middle it's shrewd' is the wordplay.
'choose' becomes 'elect' (electing is a kind of choosing).
'in the middle' indicates the central letters.
'it's shrewd' becomes 'cute' (I've seen this before).
The centre of 'jurors' is 'ro'.
'elect'+'ro'+'cute'='ELECTROCUTE'
'and will give them a' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for electrocute that I've seen before include "Kill using electricity" , "finish with power" , "Shock greatly!" , "Kill, injure by a shock" , "end with a shock?" .)
